* [SPARK-5729] Potential NPE in standalone REST APIAndrew Or2015-02-101-1/+1
| | | | | | | | | | If the user specifies a bad REST URL, the server will throw an NPE instead of propagating the error back. This is because the default `ErrorServlet` has the wrong prefix. This is a one line fix. I am will add more comprehensive tests in a separate patch.

* [SPARK-4879] Use driver to coordinate Hadoop output committing for ↵mcheah2015-02-1012-23/+549
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | speculative tasks Previously, SparkHadoopWriter always committed its tasks without question. The problem is that when speculation is enabled sometimes this can result in multiple tasks committing their output to the same file. Even though an HDFS-writing task may be re-launched due to speculation, the original task is not killed and may eventually commit as well. This can cause strange race conditions where multiple tasks that commit interfere with each other, with the result being that some partition files are actually lost entirely. For more context on these kinds of scenarios, see SPARK-4879. In Hadoop MapReduce jobs, the application master is a central coordinator that authorizes whether or not any given task can commit. Before a task commits its output, it queries the application master as to whether or not such a commit is safe, and the application master does bookkeeping as tasks are requesting commits. Duplicate tasks that would write to files that were already written to from other tasks are prohibited from committing. This patch emulates that functionality - the crucial missing component was a central arbitrator, which is now a module called the OutputCommitCoordinator. The coordinator lives on the driver and the executors can obtain a reference to this actor and request its permission to commit. As tasks commit and are reported as completed successfully or unsuccessfully by the DAGScheduler, the commit coordinator is informed of the task completion events as well to update its internal state. Future work includes more rigorous unit testing and extra optimizations should this patch cause a performance regression. It is unclear what the overall cost of communicating back to the driver on every hadoop-committing task will be. It's also important for those hitting this issue to backport this onto previous version of Spark because the bug has serious consequences, that is, data is lost. Currently, the OutputCommitCoordinator is only used when `spark.speculation` is true. It can be disabled by setting `spark.hadoop.outputCommitCoordination.enabled=false` in SparkConf. This patch is an updated version of #4155 (by mccheah), which in turn was an updated version of this PR. Closes #4155.

* [SPARK-5493] [core] Add option to impersonate user.Marcelo Vanzin2015-02-108-34/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Hadoop has a feature that allows users to impersonate other users when submitting applications or talking to HDFS, for example. These impersonated users are referred generally as "proxy users". Services such as Oozie or Hive use this feature to run applications as the requesting user. This change makes SparkSubmit accept a new command line option to run the application as a proxy user. It also fixes the plumbing of the user name through the UI (and a couple of other places) to refer to the correct user running the application, which can be different than `sys.props("user.name")` even without proxies (e.g. when using kerberos).

* SPARK-4136. Under dynamic allocation, cancel outstanding executor requests ↵Sandy Ryza2015-02-105-50/+184
| | | | | | | | | | | | | | | | | | | when no longer needed This takes advantage of the changes made in SPARK-4337 to cancel pending requests to YARN when they are no longer needed. Each time the timer in `ExecutorAllocationManager` strikes, we compute `maxNumNeededExecutors`, the maximum number of executors we could fill with the current load. This is calculated as the total number of running and pending tasks divided by the number of cores per executor. If `maxNumNeededExecutors` is below the total number of running and pending executors, we call `requestTotalExecutors(maxNumNeededExecutors)` to let the cluster manager know that it should cancel any pending requests above this amount. If not, `maxNumNeededExecutors` is just used as a bound in alongside the configured `maxExecutors` to limit the number of new requests. The patch modifies the API exposed by `ExecutorAllocationClient` for requesting additional executors by moving from `requestExecutors` to `requestTotalExecutors`. This makes the communication between the `ExecutorAllocationManager` and the `YarnAllocator` easier to reason about and removes some state that needed to be kept in the `CoarseGrainedSchedulerBackend`. I think an argument can be made that this makes for a less attractive user-facing API in `SparkContext`, but I'm having trouble envisioning situations where a user would want to use either of these APIs. This will likely break some tests, but I wanted to get feedback on the approach before adding tests and polishing.

| | | | | | | | | | | | | | | | | Addresses [SPARK-1805](https://issues.apache.org/jira/browse/SPARK-1805), though doesn't resolve it completely. Error out quickly if the user asks for the master and slaves to have different AMI virtualization types, since we don't currently support that. In addition to that, we print warnings if the inputted instance types are not recognized, though I would prefer if we errored out. Elsewhere in the script it seems [we allow unrecognized instance types](https://github.com/apache/spark/blob/5de14cc2763a8211f77eeb55940dec025822eb78/ec2/spark_ec2.py#L331), though I think we should remove that. It's messy, but it should serve us until we enhance spark-ec2 to support clusters with mixed virtualization types.

* [SPARK-2996] Implement userClassPathFirst for driver, yarn.Marcelo Vanzin2015-02-0927-348/+736
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Yarn's config option `spark.yarn.user.classpath.first` does not work the same way as `spark.files.userClassPathFirst`; Yarn's version is a lot more dangerous, in that it modifies the system classpath, instead of restricting the changes to the user's class loader. So this change implements the behavior of the latter for Yarn, and deprecates the more dangerous choice. To be able to achieve feature-parity, I also implemented the option for drivers (the existing option only applies to executors). So now there are two options, each controlling whether to apply userClassPathFirst to the driver or executors. The old option was deprecated, and aliased to the new one (`spark.executor.userClassPathFirst`). The existing "child-first" class loader also had to be fixed. It didn't handle resources, and it was also doing some things that ended up causing JVM errors depending on how things were being called.

* [SPARK-5614][SQL] Predicate pushdown through Generate.Lu Yan2015-02-092-1/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now in Catalyst's rules, predicates can not be pushed through "Generate" nodes. Further more, partition pruning in HiveTableScan can not be applied on those queries involves "Generate". This makes such queries very inefficient. In practice, it finds patterns like ```scala Filter(predicate, Generate(generator, _, _, _, grandChild)) ``` and splits the predicate into 2 parts by referencing the generated column from Generate node or not. And a new Filter will be created for those conjuncts can be pushed beneath Generate node. If nothing left for the original Filter, it will be removed. For example, physical plan for query ```sql select len, bk from s_server lateral view explode(len_arr) len_table as len where len > 5 and day = '20150102'; ``` where 'day' is a partition column in metastore is like this in current version of Spark SQL: > Project [len, bk] > > Filter ((len > "5") && "(day = "20150102")") > > Generate explode(len_arr), true, false > > HiveTableScan [bk, len_arr, day], (MetastoreRelation default, s_server, None), None But theoretically the plan should be like this > Project [len, bk] > > Filter (len > "5") > > Generate explode(len_arr), true, false > > HiveTableScan [bk, len_arr, day], (MetastoreRelation default, s_server, None), Some(day = "20150102") Where partition pruning predicates can be pushed to HiveTableScan nodes.
