             Summary: Big Trunk unit tests failing with "OutOfMemoryError: unable to create new native thread"
                 Key: HBASE-14262
                 URL: https://issues.apache.org/jira/browse/HBASE-14262
             Project: HBase
          Issue Type: Bug
          Components: test
            Reporter: stack
            Assignee: stack


The bit unit tests are coming in with OOME, can't create native threads.

I was also getting the OOME locally running on MBP. git bisect got me to HBASE-13065, where we upped the test heap for TestDistributedLogSplitting back in feb. Around the time that this went in, we had similar OOME issues but then it was because we were doing 32bit JVMs. It does not seem to be the case here.

A recent run failed all the below and most are OOME:
