* [SPARK-7003] Improve reliability of connection failure detection between ↵Aaron Davidson2015-04-207-18/+375
| | | | | | | | | | | | | | | | | Netty block transfer service endpoints Currently we rely on the assumption that an exception will be raised and the channel closed if two endpoints cannot communicate over a Netty TCP channel. However, this guarantee does not hold in all network environments, and [SPARK-6962](https://issues.apache.org/jira/browse/SPARK-6962) seems to point to a case where only the server side of the connection detected a fault. This patch improves robustness of fetch/rpc requests by having an explicit timeout in the transport layer which closes the connection if there is a period of inactivity while there are outstanding requests. NB: This patch is actually only around 50 lines added if you exclude the testing-related code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a PR for cleaning up and finalizing the DecisionTree API. PRs for ensembles will follow once this is merged. ### Goal Here is the description copied from the JIRA (for both trees and ensembles): > **Issue**: The APIs for DecisionTree and ensembles (RandomForests and GradientBoostedTrees) have been experimental for a long time. The API has become very convoluted because trees and ensembles have many, many variants, some of which we have added incrementally without a long-term design. > **Proposal**: This JIRA is for discussing changes required to finalize the APIs. After we discuss, I will make a PR to update the APIs and make them non-Experimental. This will require making many breaking changes; see the design doc for details. > **[Design doc](https://docs.google.com/document/d/1rJ_DZinyDG3PkYkAKSsQlY0QgCeefn4hUv7GsPkzBP4)** : This outlines current issues and the proposed API. Overall code layout: * The old API in mllib.tree.* will remain the same. * The new API will reside in ml.classification.* and ml.regression.* ### Summary of changes Old API * Exactly the same, except I made 1 method in Loss private (but that is not a breaking change since that method was introduced after the Spark 1.3 release). New APIs * Under Pipeline API * The new API preserves functionality, except: * New API does NOT store prob (probability of label in classification). I want to have it store the full vector of probabilities but feel that should be in a later PR. * Use abstractions for parameters, estimators, and models to avoid code duplication * Limit parameters to relevant algorithms * For enum-like types, only expose Strings * We can make these pluggable later on by adding new parameters. That is a far-future item. Test suites * I organized DecisionTreeSuite, but I made absolutely no changes to the tests themselves. * The test suites for the new API only test (a) similarity with the results of the old API and (b) elements of the new API. * After code is moved to this new API, we should move the tests from the old suites which test the internals. ### Details #### Changed names Parameters * useNodeIdCache -> cacheNodeIds #### Other changes * Split: Changed categories to set instead of list #### Non-decision tree changes * AttributeGroup * Added parentheses to toMetadata, toStructField methods (These were removed in a previous PR, but I ran into 1 issue with the Scala compiler not being able to disambiguate between a toMetadata method with no parentheses and a toMetadata method which takes 1 argument.) * Attributes * Renamed: toMetadata -> toMetadataImpl * Added toMetadata methods which return ML metadata (keyed with “ML_ATTR”) * NominalAttribute: Added getNumValues method which examines both numValues and values. * Params.inheritValues: Checks whether the parent param really belongs to the child (to allow Estimator-Model pairs with different sets of parameters) ### Questions for reviewers * Is "DecisionTreeClassificationModel" too long a name? * Is this OK in the docs? ``` class DecisionTreeRegressor extends TreeRegressor[DecisionTreeRegressionModel] with DecisionTreeParams[DecisionTreeRegressor] with TreeRegressorParams[DecisionTreeRegressor] ``` ### Future We should open up the abstractions at some point. E.g., it would be useful to be able to set tree-related parameters in 1 place and then pass those to multiple tree-based algorithms. Follow-up JIRAs will be (in this order): * Tree ensembles * Deprecate old tree code * Move DecisionTree implementation code to new API. * Move tests from the old suites which test the internals. * Update programming guide * Python API * Change RandomForest* to always use bootstrapping, even when numTrees = 1 * Provide the probability of the predicted label for classification. After we move code to the new API and update it to maintain probabilities for all labels, then we can add the probabilities to the new API.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when Spark launches the Yarn AM, the process will use the local Hadoop configuration on the node where the AM launches, if one is present. A more correct approach is to use the same configuration used to launch the Spark job, since the user may have made modifications (such as adding app-specific configs). The approach taken here is to use the distributed cache to make all files in the Hadoop configuration directory available to the AM. This is a little overkill since only the AM needs them (the executors use the broadcast Hadoop configuration from the driver), but is the easier approach. Even though only a few files in that directory may end up being used, all of them are uploaded. This allows supporting use cases such as when auxiliary configuration files are used for SSL configuration, or when uploading a Hive configuration directory. Not all of these may be reflected in a o.a.h.conf.Configuration object, but may be needed when a driver in cluster mode instantiates, for example, a HiveConf object instead.

* [SPARK-6952] Handle long args when detecting PID reusePunya Biswal2015-04-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | sbin/spark-daemon.sh used ps -p "$TARGET_PID" -o args= to figure out whether the process running with the expected PID is actually a Spark daemon. When running with a large classpath, the output of ps gets truncated and the check fails spuriously. This weakens the check to see if it's a java command (which is something we do in other parts of the script) rather than looking for the specific main class name. This means that SPARK-4832 might happen under a slightly broader range of circumstances (a java program happened to reuse the same PID), but it seems worthwhile compared to failing consistently with a large classpath.

* [SPARK-4194] [core] Make SparkContext initialization exception-safe.Marcelo Vanzin2015-04-166-244/+329
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SparkContext has a very long constructor, where multiple things are initialized, multiple threads are spawned, and multiple opportunities for exceptions to be thrown exist. If one of these happens at an innoportune time, lots of garbage tends to stick around. This patch re-organizes SparkContext so that its internal state is initialized in a big "try" block. The fields keeping state are now completely private to SparkContext, and are "vars", because Scala doesn't allow you to initialize a val later. The existing API interface is kept by turning vals into defs (which works because Scala guarantees the same binary interface for those). On top of that, a few things in other areas were changed to avoid more things leaking: - Executor was changed to explicitly wait for the heartbeat thread to stop. LocalBackend was changed to wait for the "StopExecutor" message to be received, since otherwise there could be a race between that message arriving and the actor system being shut down. - ConnectionManager could possibly hang during shutdown, because an interrupt at the wrong moment could cause the selector thread to still call select and then wait forever. So also wake up the selector so that this situation is avoided.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks for the initial work from Ishiihara in #3173 This PR introduce a new join method of sort merge join, which firstly ensure that keys of same value are in the same partition, and inside each partition the Rows are sorted by key. Then we can run down both sides together, find matched rows using [sort merge join](http://en.wikipedia.org/wiki/Sort-merge_join). In this way, we don't have to store the whole hash table of one side as hash join, thus we have less memory usage. Also, this PR would benefit from #3438 , making the sorting phrase much more efficient. We introduced a new configuration of "spark.sql.planner.sortMergeJoin" to switch between this(`true`) and ShuffledHashJoin(`false`), probably we want the default value of it be `false` at first.
