Subject [jira] Commented: (PIG-1209) Port POJoinPackage to proactively spill
Date Thu, 04 Feb 2010 03:24:28 GMT

    [ https://issues.apache.org/jira/browse/PIG-1209?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12829415#action_12829415

Ashutosh Chauhan commented on PIG-1209:
---------------------------------------

Did manual testing on this. With large enough dataset some reducers fail with "Error: GC overhead
limit exceeded". After applying this patch, those failures didn't happen. This patch is ready
for review.

> POPackage proactively spills the bag whereas POJoinPackage still uses the SpillableMemoryManager.
We should port this to use InternalCacheBag which proactively spills.
