Subject [Impala-ASF-CR] IMPALA-5080: OutOfMemory PermGen space
Date Fri, 14 Apr 2017 21:48:29 GMT
Hello Matthew Jacobs,

I'd like you to reexamine a change.  Please visit

    http://gerrit.cloudera.org:8080/6642

to look at the new patch set (#2).

IMPALA-5080: OutOfMemory PermGen space

The problem is that over time our usage of PermGen space has
gradually gone up, recently hitting a point where we may run
out during testing. The fix is to increase the allowed max
perm gen space.

The default is 64mb on 32bit systems and 82mb on 64bit systems.
After bumping it up to 128mb, I haven't seen any failures on my
machine.

I also verified that this is not a leak by running the test,
test_java_udfs, 10 times, checking the perm gen usage with jmap,
running it a further 300 times, and checking that the perm gen
usage remained the same.
