Description

On Andrew Purtell's linux he sees this when he runs TestMemstoreLABWithoutPool (See thread "[VOTE] The second hbase-2.0.0-beta-1 Release Candidate is available for download"):

TestMemstoreLABWithoutPool.org.apache.hadoop.hbase.regionserver.TestMemstoreLABWithoutPool
can fail with OOME if not run in isolation.

If run in isolation, I get

org.apache.hadoop.hbase.regionserver.TestMemstoreLABWithoutPool.testLABChunkQueueWithMultipleMSLABs(org.apache.hadoop.hbase.regionserver.TestMemstoreLABWithoutPool)
[ERROR]   Run 1:
TestMemstoreLABWithoutPool.testLABChunkQueueWithMultipleMSLABs:143 All the
chunks must have been cleared
[ERROR]   Run 2:
TestMemstoreLABWithoutPool.testLABChunkQueueWithMultipleMSLABs:143 All the
chunks must have been cleared
[ERROR]   Run 3:
TestMemstoreLABWithoutPool.testLABChunkQueueWithMultipleMSLABs:143 All the
chunks must have been cleared
[ERROR]   Run 4:
TestMemstoreLABWithoutPool.testLABChunkQueueWithMultipleMSLABs:143 All the
chunks must have been cleared

It runs fine for me on my linux and mac. ram_krish / anastas ? You see any of this?

Going to disable this test in meantime.... in subissue.
