| | | | | | | | | | | | | | The executors and the driver may not share the same Spark home. There is currently one way to set the executor side Spark home in Mesos, through setting `spark.home`.

* [SPARK-3240] Adding known issue for MESOS-1688Martin Weindel2014-08-261-0/+2
| | | | | | | | | | | | | | When using Mesos with the fine-grained mode, a Spark job can run into a dead lock on low allocatable memory on Mesos slaves. As a work-around 32 MB (= Mesos MIN_MEM) are allocated for each task, to ensure Mesos making new offers after task completion. From my perspective, it would be better to fix this problem in Mesos by dropping the constraint on memory for offers, but as temporary solution this patch helps to avoid the dead lock on current Mesos versions. See [[MESOS-1688] No offers if no memory is allocatable](https://issues.apache.org/jira/browse/MESOS-1688) for details for this problem.

* SPARK-3092 [SQL]: Always include the thriftserver when -Phive is enabled.Patrick Wendell2014-08-202-9/+3
| | | | | | | | | | | | | Currently we have a separate profile called hive-thriftserver. I originally suggested this in case users did not want to bundle the thriftserver, but it's ultimately lead to a lot of confusion. Since the thriftserver is only a few classes, I don't see a really good reason to isolate it from the rest of Hive. So let's go ahead and just include it in the same profile to simplify things. This has been suggested in the past by liancheng.

* [SPARK-3029] Disable local execution of Spark jobs by defaultAaron Davidson2014-08-141-0/+9
| | | | | | | | | | | | | | | Currently, local execution of Spark jobs is only used by take(), and it can be problematic as it can load a significant amount of data onto the driver. The worst case scenarios occur if the RDD is cached (guaranteed to load whole partition), has very large elements, or the partition is just large and we apply a filter with high selectivity or computational overhead. Additionally, jobs that run locally in this manner do not show up in the web UI, and are thus harder to track or understand what is occurring. This PR adds a flag to disable local execution, which is turned OFF by default, with the intention of perhaps eventually removing this functionality altogether. Removing it now is a tougher proposition since it is part of the public runJob API. An alternative solution would be to limit the flag to take()/first() to avoid impacting any external users of this API, but such usage (or, at least, reliance upon the feature) is hopefully minimal.

* SPARK-2787: Make sort-based shuffle write files directly when there's no ↵Matei Zaharia2014-08-071-0/+18
| | | | | | | | | | | | | | | | | | | | sorting/aggregation and # partitions is small As described in https://issues.apache.org/jira/browse/SPARK-2787, right now sort-based shuffle is more expensive than hash-based for map operations that do no partial aggregation or sorting, such as groupByKey. This is because it has to serialize each data item twice (once when spilling to intermediate files, and then again when merging these files object-by-object). This patch adds a code path to just write separate files directly if the # of output partitions is small, and concatenate them at the end to produce a sorted file. On the unit test side, I added some tests that force or don't force this bypass path to be used, and checked that our tests for other features (e.g. all the operations) cover both cases.

* [SPARK-2157] Enable tight firewall rules for SparkAndrew Or2014-08-063-90/+179
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The goal of this PR is to allow users of Spark to write tight firewall rules for their clusters. This is currently not possible because Spark uses random ports in many places, notably the communication between executors and drivers. The changes in this PR are based on top of ash211's changes in #1107. The list covered here may or may not be the complete set of port needed for Spark to operate perfectly. However, as of the latest commit there are no known sources of random ports (except in tests). I have not documented a few of the more obscure configs. My spark-env.sh looks like this: ``` export SPARK_MASTER_PORT=6060 export SPARK_WORKER_PORT=7070 export SPARK_MASTER_WEBUI_PORT=9090 export SPARK_WORKER_WEBUI_PORT=9091 ``` and my spark-defaults.conf looks like this: ``` spark.master spark://andrews-mbp:6060 spark.driver.port 5001 spark.fileserver.port 5011 spark.broadcast.port 5021 spark.replClassServer.port 5031 spark.blockManager.port 5041 spark.executor.port 5051 ``` Author: Andrew Or <andrewor14@gmail.com> Author: Andrew Ash <andrew@andrewash.com> Closes #1777 from andrewor14/configure-ports and squashes the following commits: 621267b [Andrew Or] Merge branch 'master' of github.com:apache/spark into configure-ports 8a6b820 [Andrew Or] Use a random UI port during tests 7da0493 [Andrew Or] Fix tests 523c30e [Andrew Or] Add test for isBindCollision b97b02a [Andrew Or] Minor fixes c22ad00 [Andrew Or] Merge branch 'master' of github.com:apache/spark into configure-ports 93d359f [Andrew Or] Executors connect to wrong port when collision occurs d502e5f [Andrew Or] Handle port collisions when creating Akka systems a2dd05c [Andrew Or] Patrick's comment nit 86461e2 [Andrew Or] Remove spark.executor.env.port and spark.standalone.client.port 1d2d5c6 [Andrew Or] Fix ports for standalone cluster mode cb3be88 [Andrew Or] Various doc fixes (broken link, format etc.) e837cde [Andrew Or] Remove outdated TODOs bfbab28 [Andrew Or] Merge branch 'master' of github.com:apache/spark into configure-ports de1b207 [Andrew Or] Update docs to reflect new ports b565079 [Andrew Or] Add spark.ports.maxRetries 2551eb2 [Andrew Or] Remove spark.worker.watcher.port 151327a [Andrew Or] Merge branch 'master' of github.com:apache/spark into configure-ports 9868358 [Andrew Or] Add a few miscellaneous ports 6016e77 [Andrew Or] Add spark.executor.port 8d836e6 [Andrew Or] Also document SPARK_{MASTER/WORKER}_WEBUI_PORT 4d9e6f3 [Andrew Or] Fix super subtle bug 3f8e51b [Andrew Or] Correct erroneous docs... e111d08 [Andrew Or] Add names for UI services 470f38c [Andrew Or] Special case non-"Address already in use" exceptions 1d7e408 [Andrew Or] Treat 0 ports specially + return correct ConnectionManager port ba32280 [Andrew Or] Minor fixes 6b550b0 [Andrew Or] Assorted fixes 73fbe89 [Andrew Or] Move start service logic to Utils ec676f4 [Andrew Or] Merge branch 'SPARK-2157' of github.com:ash211/spark into configure-ports 038a579 [Andrew Ash] Trust the server start function to report the port the service started on 7c5bdc4 [Andrew Ash] Fix style issue 0347aef [Andrew Ash] Unify port fallback logic to a single place 24a4c32 [Andrew Ash] Remove type on val to match surrounding style 9e4ad96 [Andrew Ash] Reformat for style checker 5d84e0e [Andrew Ash] Document new port configuration options 066dc7a [Andrew Ash] Fix up HttpServer port increments cad16da [Andrew Ash] Add fallover increment logic for HttpServer c5a0568 [Andrew Ash] Fix ConnectionManager to retry with increment b80d2fd [Andrew Ash] Make Spark's block manager port configurable 17c79bb [Andrew Ash] Add a configuration option for spark-shell's class server f34115d [Andrew Ash] SPARK-1176 Add port configuration for HttpBroadcast 49ee29b [Andrew Ash] SPARK-1174 Add port configuration for HttpFileServer 1c0981a [Andrew Ash] Make port in HttpServer configurable

* SPARK-2380: Support displaying accumulator values in the web UIPatrick Wendell2014-08-051-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for giving accumulators user-visible names and displaying accumulator values in the web UI. This allows users to create custom counters that can display in the UI. The current approach displays both the accumulator deltas caused by each task and a "current" value of the accumulator totals for each stage, which gets update as tasks finish. Currently in Spark developers have been extending the `TaskMetrics` functionality to provide custom instrumentation for RDD's. This provides a potentially nicer alternative of going through the existing accumulator framework (actually `TaskMetrics` and accumulators are on an awkward collision course as we add more features to the former). The current patch demo's how we can use the feature to provide instrumentation for RDD input sizes. The nice thing about going through accumulators is that users can read the current value of the data being tracked in their programs. This could be useful to e.g. decide to short-circuit a Spark stage depending on how things are going. ![counters](https://cloud.githubusercontent.com/assets/320616/3488815/6ee7bc34-0505-11e4-84ce-e36d9886e2cf.png) Author: Patrick Wendell <pwendell@gmail.com> Closes #1309 from pwendell/metrics and squashes the following commits: 8815308 [Patrick Wendell] Merge remote-tracking branch 'apache/master' into HEAD 93fbe0f [Patrick Wendell] Other minor fixes cc43f68 [Patrick Wendell] Updating unit tests c991b1b [Patrick Wendell] Moving some code into the Accumulators class 9a9ba3c [Patrick Wendell] More merge fixes c5ace9e [Patrick Wendell] More merge conflicts 1da15e3 [Patrick Wendell] Merge remote-tracking branch 'apache/master' into metrics 9860c55 [Patrick Wendell] Potential solution to posting listener events 0bb0e33 [Patrick Wendell] Remove "display" variable and assume display = name.isDefined 0ec4ac7 [Patrick Wendell] Java API's e95bf69 [Patrick Wendell] Stash be97261 [Patrick Wendell] Style fix 8407308 [Patrick Wendell] Removing examples in Hadoop and RDD class 64d405f [Patrick Wendell] Adding missing file 5d8b156 [Patrick Wendell] Changes based on Kay's review. 9f18bad [Patrick Wendell] Minor style changes and tests 7a63abc [Patrick Wendell] Adding Json serialization and responding to Reynold's feedback ad85076 [Patrick Wendell] Example of using named accumulators for custom RDD metrics. 0b72660 [Patrick Wendell] Initial WIP example of supporing globally named accumulators.

| | | | | | | | | | | | | | | | | | | It was easier to combine these 2 jira since they touch many of the same places. This pr adds the following: - adds modify acls - adds admin acls (list of admins/users that get added to both view and modify acls) - modify Kill button on UI to take modify acls into account - changes config name of spark.ui.acls.enable to spark.acls.enable since I choose poorly in original name. We keep backwards compatibility so people can still use spark.ui.acls.enable. The acls should apply to any web ui as well as any CLI interfaces. - send view and modify acls information on to YARN so that YARN interfaces can use (yarn cli for killing applications for example).

* SPARK-2792. Fix reading too much or too little data from each stream in ↵Matei Zaharia2014-08-041-1/+1
| | | | | | | | | | | | | | | | | | | | ExternalMap / Sorter All these changes are from mridulm's work in #1609, but extracted here to fix this specific issue and make it easier to merge not 1.1. This particular set of changes is to make sure that we read exactly the right range of bytes from each spill file in EAOM: some serializers can write bytes after the last object (e.g. the TC_RESET flag in Java serialization) and that would confuse the previous code into reading it as part of the next batch. There are also improvements to cleanup to make sure files are closed. In addition to bringing in the changes to ExternalAppendOnlyMap, I also copied them to the corresponding code in ExternalSorter and updated its test suite to test for the same issues.

* [SPARK-2784][SQL] Deprecate hql() method in favor of a config option, ↵Michael Armbrust2014-08-031-9/+9
| | | | | | | | | | | | | | | | | | | | 'spark.sql.dialect' Many users have reported being confused by the distinction between the `sql` and `hql` methods. Specifically, many users think that `sql(...)` cannot be used to read hive tables. In this PR I introduce a new configuration option `spark.sql.dialect` that picks which dialect with be used for parsing. For SQLContext this must be set to `sql`. In `HiveContext` it defaults to `hiveql` but can also be set to `sql`. The `hql` and `hiveql` methods continue to act the same but are now marked as deprecated. **This is a possibly breaking change for some users unless they set the dialect manually, though this is unlikely.** For example: `hiveContex.sql("SELECT 1")` will now throw a parsing exception by default.
