Subject [jira] Commented: (PIG-1348) InternalCachedBag running out of memory
Date Sat, 03 Apr 2010 00:14:27 GMT

Richard Ding commented on PIG-1348:
-----------------------------------

The problem seems not with the InternalCachedBag.  The same script runs fine when replacing
the store command with the dump command.

> 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.
