Pete Wyckoff commented on HADOOP-4775:
--------------------------------------
Hi Brian,
Have you tried 4616 and 4635 patches?
4616 fixes a memory leak of a group name and 4635 fixes a memory leak of not
detroying a mutex.
you could also compile with -Dlibhdfs.noperms=1 just to ensure it isn't related
to groups.
When investigating 4635, we saw that it's very hard to judge fuse-dfs's use of
memory because of the JVM GC of the DFSClient is hard to judge.
