* [SPARK-13308] ManagedBuffers passed to OneToOneStreamManager need to be ↵Josh Rosen2016-02-167-9/+119
| | | | | | | | | | | | | | freed in non-error cases ManagedBuffers that are passed to `OneToOneStreamManager.registerStream` need to be freed by the manager once it's done using them. However, the current code only frees them in certain error-cases and not during typical operation. This isn't a major problem today, but it will cause memory leaks after we implement better locking / pinning in the BlockManager (see #10705). This patch modifies the relevant network code so that the ManagedBuffers are freed as soon as the messages containing them are processed by the lower-level Netty message sending code. /cc zsxwing for review.

* [SPARK-13018][DOCS] Replace example code in mllib-pmml-model-export.md using ↵Xin Ren2016-02-152-32/+62
| | | | | | | | | | | | | | | | | | | | | include_example Replace example code in mllib-pmml-model-export.md using include_example https://issues.apache.org/jira/browse/SPARK-13018 The example code in the user guide is embedded in the markdown and hence it is not easy to test. It would be nice to automatically test them. This JIRA is to discuss options to automate example code testing and see what we can do in Spark 1.6. Goal is to move actual example code to spark/examples and test compilation in Jenkins builds. Then in the markdown, we can reference part of the code to show in the user guide. This requires adding a Jekyll tag that is similar to https://github.com/jekyll/jekyll/blob/master/lib/jekyll/tags/include.rb, e.g., called include_example. `{% include_example scala/org/apache/spark/examples/mllib/PMMLModelExportExample.scala %}` Jekyll will find `examples/src/main/scala/org/apache/spark/examples/mllib/PMMLModelExportExample.scala` and pick code blocks marked "example" and replace code block in `{% highlight %}` in the markdown.

* [SPARK-12503][SPARK-12505] Limit pushdown in UNION ALL and OUTER JOINJosh Rosen2016-02-146-9/+294
| | | | | | | | | | | | | | | This patch adds a new optimizer rule for performing limit pushdown. Limits will now be pushed down in two cases: - If a limit is on top of a `UNION ALL` operator, then a partition-local limit operator will be pushed to each of the union operator's children. - If a limit is on top of an `OUTER JOIN` then a partition-local limit will be pushed to one side of the join. For `LEFT OUTER` and `RIGHT OUTER` joins, the limit will be pushed to the left and right side, respectively. For `FULL OUTER` join, we will only push limits when at most one of the inputs is already limited: if one input is limited we will push a smaller limit on top of it and if neither input is limited then we will limit the input which is estimated to be larger. These optimizations were proposed previously by gatorsmile in #10451 and #10454, but those earlier PRs were closed and deferred for later because at that time Spark's physical `Limit` operator would trigger a full shuffle to perform global limits so there was a chance that pushdowns could actually harm performance by causing additional shuffles/stages. In #7334, we split the `Limit` operator into separate `LocalLimit` and `GlobalLimit` operators, so we can now push down only local limits (which don't require extra shuffles). This patch is based on both of gatorsmile's patches, with changes and simplifications due to partition-local-limiting. When we push down the limit, we still keep the original limit in place, so we need a mechanism to ensure that the optimizer rule doesn't keep pattern-matching once the limit has been pushed down. In order to handle this, this patch adds a `maxRows` method to `SparkPlan` which returns the maximum number of rows that the plan can compute, then defines the pushdown rules to only push limits to children if the children's maxRows are greater than the limit's maxRows. This idea is carried over from #10451; see that patch for additional discussion. Author: Josh Rosen <joshrosen@databricks.com> Closes #11121 from JoshRosen/limit-pushdown-2.
* [SPARK-13185][SQL] Reuse Calendar object in DateTimeUtils.StringToDate ↵Carson Wang2016-02-141-1/+9
| | | | | | | | | | | | method to improve performance The java `Calendar` object is expensive to create. I have a sub query like this `SELECT a, b, c FROM table UV WHERE (datediff(UV.visitDate, '1997-01-01')>=0 AND datediff(UV.visitDate, '2015-01-01')<=0))` The table stores `visitDate` as String type and has 3 billion records. A `Calendar` object is created every time `DateTimeUtils.stringToDate` is called. By reusing the `Calendar` object, I saw about 20 seconds performance improvement for this stage.
