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.
> TestLogRolling#testLogRollOnDatanodeDeath test failure
> ------------------------------------------------------
>
> Key: HBASE-10142
> URL: https://issues.apache.org/jira/browse/HBASE-10142
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.98.0, 0.99.0
> Reporter: Andrew Purtell
> Fix For: 0.98.0
>
>
> 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.
