* Add/increase severity of warning in documentation of groupBy()Aaron Davidson2014-07-142-9/+21
| | | | | | | | | | | | | | | | | | groupBy()/groupByKey() is notorious for being a very convenient API that can lead to poor performance when used incorrectly. This PR just makes it clear that users should be cautious not to rely on this API when they really want a different (more performant) one, such as reduceByKey(). (Note that one source of confusion is the name; this groupBy() is not the same as a SQL GROUP-BY, which is used for aggregation and is more similar in nature to Spark's reduceByKey().)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fix obtains a comparable performance boost as [PR #1390](https://github.com/apache/spark/pull/1390) by moving an array update and deserializer initialization out of a potentially very long loop. Suggested by yhuai. The below results are updated for this fix. ## Benchmarks Generated a local text file with 10M rows of simple key-value pairs. The data is loaded as a table through Hive.

| | | | | | | | | | | | | | | | | | Fixes test failures introduced by https://github.com/apache/spark/pull/1316. For both the regression and classification cases, val stats is the InformationGainStats for the best tree split. stats.predict is the predicted value for the data, before the split is made. Since 600 of the 1,000 values generated by DecisionTreeSuite.generateCategoricalDataPoints() are 1.0 and the rest 0.0, the regression tree and classification tree both correctly predict a value of 0.6 for this data now, and the assertions have been changed to reflect that.

* [SPARK-2152][MLlib] fix bin offset in DecisionTree node aggregations (also ↵johnnywalleye2014-07-081-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | resolves SPARK-2160) Hi, this pull fixes (what I believe to be) a bug in DecisionTree.scala. In the extractLeftRightNodeAggregates function, the first set of rightNodeAgg values for Regression are set in line 792 as follows: rightNodeAgg(featureIndex)(2 * (numBins - 2)) = binData(shift + (2 * numBins - 1))) Then there is a loop that sets the rest of the values, as in line 809: rightNodeAgg(featureIndex)(2 * (numBins - 2 - splitIndex)) = binData(shift + (2 *(numBins - 2 - splitIndex))) + rightNodeAgg(featureIndex)(2 * (numBins - 1 - splitIndex)) But since splitIndex starts at 1, this ends up skipping a set of binData values. The changes here address this issue, for both the Regression and Classification cases.

Then, we convert the table alias to lower case no matter if the parser is case sensitive or not. To see the issue ... ``` val sqlContext = new org.apache.spark.sql.SQLContext(sc) import sqlContext.createSchemaRDD case class Person(name: String, age: Int) val people = sc.textFile("examples/src/main/resources/people.txt").map(_.split(",")).map(p => Person(p(0), p(1).trim.toInt)) people.registerAsTable("people") sqlContext.sql("select PEOPLE.name from people PEOPLE") ``` The plan is ... ``` == Query Plan == Project ['PEOPLE.name] ExistingRdd [name#0,age#1], MapPartitionsRDD[4] at mapPartitions at basicOperators.scala:176 ``` You can find that `PEOPLE.name` is not resolved. This PR introduces three changes. 1. If a table has an alias, the catalog will not lowercase the alias. If a lowercase alias is needed, the analyzer will do the work. 2. A catalog has a new val caseSensitive that indicates if this catalog is case sensitive or not. For example, a SimpleCatalog is case sensitive, but 3. Corresponding unit tests.

* [SPARK-2059][SQL] Don't throw TreeNodeException in `execution.ExplainCommand`Cheng Lian2014-07-031-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a fix for the problem revealed by PR #1265. Currently `HiveComparisonSuite` ignores output of `ExplainCommand` since Catalyst query plan is quite different from Hive query plan. But exceptions throw from `CheckResolution` still breaks test cases. This PR catches any `TreeNodeException` and reports it as part of the query explanation. After merging this PR, PR #1265 can also be merged safely. For a normal query: ``` scala> hql("explain select key from src").foreach(println) ... [Physical execution plan:] [HiveTableScan [key#9], (MetastoreRelation default, src, None), None] ``` For a wrong query with unresolved attribute(s): ``` scala> hql("explain select kay from src").foreach(println) ...

* SPARK-2282: Reuse PySpark Accumulator sockets to avoid crashing SparkAaron Davidson2014-07-031-0/+2
| | | | | | | | | | | | | | | | | JIRA: https://issues.apache.org/jira/browse/SPARK-2282 This issue is caused by a buildup of sockets in the TIME_WAIT stage of TCP, which is a stage that lasts for some period of time after the communication closes. This solution simply allows us to reuse sockets that are in TIME_WAIT, to avoid issues with the buildup of the rapid creation of these sockets. Author: Aaron Davidson <aaron@databricks.com> Closes #1220 from aarondav/SPARK-2282 and squashes the following commits: 2e5cab3 [Aaron Davidson] SPARK-2282: Reuse PySpark Accumulator sockets to avoid crashing Spark (cherry picked from commit 97a0bfe1c0261384f09d53f9350de52fb6446d59) Signed-off-by: Patrick Wendell <pwendell@gmail.com>
* [SPARK-2307][Reprise] Correctly report RDD blocks on SparkUIAndrew Or2014-07-036-23/+184
| | | | | | | | | | | | | | | | | | | | | | | | **Problem.** The existing code in `ExecutorPage.scala` requires a linear scan through all the blocks to filter out the uncached ones. Every refresh could be expensive if there are many blocks and many executors. **Solution.** The proper semantics should be the following: `StorageStatusListener` should contain only block statuses that are cached. This means as soon as a block is unpersisted by any mean, its status should be removed. This is reflected in the changes made in `StorageStatusListener.scala`. Further, the `StorageTab` must stop relying on the `StorageStatusListener` changing a dropped block's status to `StorageLevel.NONE` (which no longer happens). This is reflected in the changes made in `StorageTab.scala` and `StorageUtils.scala`. ---------- If you have been following this chain of PRs like pwendell, you will quickly notice that this reverts the changes in #1249, which reverts the changes in #1080. In other words, we are adding back the changes from #1080, and fixing SPARK-2307 on top of those changes. Please ask questions if you are confused.
