[SPARK-7490] [CORE] [Minor] MapOutputTracker.deserializeMapStatuses: close input streams GZIPInputStream allocates native memory that is not freed until close() or when the finalizer runs. It is best to close() these streams explicitly. stephenh made the same change for serializeMapStatuses in commit b0d884f0. This is the same change for deserialize. (I ran the unit test suite! it seems to have passed. I did not make a JIRA since this seems "trivial", and the guidelines suggest it is not required for trivial changes) Author: Evan Jones <ejo...@twitter.com> Closes #5982 from evanj/master and squashes the following commits: 0d76e85 [Evan Jones] [CORE] MapOutputTracker.deserializeMapStatuses: close input streams (cherry picked from commit 25889d8d97094325f10fbf52f3b36412f212eeb2) Signed-off-by: Sean Owen <so...@cloudera.com> Project: http://git-wip-us.apache.org/repos/asf/spark/repo Commit: http://git-wip-us.apache.org/repos/asf/spark/commit/ef4a0ea7 Tree: http://git-wip-us.apache.org/repos/asf/spark/tree/ef4a0ea7 Diff: http://git-wip-us.apache.org/repos/asf/spark/diff/ef4a0ea7 Branch: refs/heads/branch-1.3 Commit: ef4a0ea7bab19d5ec8ecad3ff4f8556361abeebe Parents: 7fd212b Author: Evan Jones <ejo...@twitter.com> Authored: Fri May 8 22:00:39 2015 +0100 Committer: Sean Owen <so...@cloudera.com> Committed: Fri May 8 22:01:19 2015 +0100 ---------------------------------------------------------------------- core/src/main/scala/org/apache/spark/MapOutputTracker.scala | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) ---------------------------------------------------------------------- http://git-wip-us.apache.org/repos/asf/spark/blob/ef4a0ea7/core/src/main/scala/org/apache/spark/MapOutputTracker.scala ---------------------------------------------------------------------- diff --git a/core/src/main/scala/org/apache/spark/MapOutputTracker.scala b/core/src/main/scala/org/apache/spark/MapOutputTracker.scala index 6e4edc7..a50c28b 100644 --- a/core/src/main/scala/org/apache/spark/MapOutputTracker.scala +++ b/core/src/main/scala/org/apache/spark/MapOutputTracker.scala @@ -367,7 +367,11 @@ private[spark] object MapOutputTracker extends Logging { // Opposite of serializeMapStatuses. def deserializeMapStatuses(bytes: Array[Byte]): Array[MapStatus] = { val objIn = new ObjectInputStream(new GZIPInputStream(new ByteArrayInputStream(bytes))) - objIn.readObject().asInstanceOf[Array[MapStatus]] + Utils.tryWithSafeFinally { + objIn.readObject().asInstanceOf[Array[MapStatus]] + } { + objIn.close() + } } // Convert an array of MapStatuses to locations and sizes for a given reduce ID.
