InternalCachedBag running out of memory
---------------------------------------
Key: PIG-1348
URL: https://issues.apache.org/jira/browse/PIG-1348
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.7.0
Reporter: Ashutosh Chauhan
Assignee: Richard Ding
InternalCachedBag makes estimate of memory available to the VM by using
Runtime.getRuntime().maxMemory(). It then uses 10%(by default, though
configurable) of this memory and divides this memory into number of bags. It
keeps track of the memory used by bags and then proactively spills if bags
memory usage reach close to these limits. Given all this in theory when
presented with data more then it can handle InternalCachedBag should not run
out of memory. But in practice we find OOM happening.
