Andrew Purtell commented on HBASE-10142:
----------------------------------------

The Jenkins slaves running this test were JDK 6. I've updated them to JDK 7u45 along with other build infrastructure and am retesting. Locally I cannot reproduce this problem after 20 iterations, continuing to 100.

> This is a demanding unit test, which fails fairly often as software versions (JVM, Hadoop) and system load change. Currently when testing 0.98 branch using Oracle JRE 1.7.0u45 I see this failure:
> {noformat}
> Failed tests:   testLogRollOnDatanodeDeath(org.apache.hadoop.hbase.regionserver.wal.TestLogRolling): LowReplication Roller should've been disabled, current replication=1
> {noformat} 
> Could be a timing issue after the recent switch to Hadoop 2 as default build/test profile. Let's see if more leniency makes sense and if it can stabilize the test before disabling it.
