Subject [jira] [Commented] (HBASE-10142) TestLogRolling#testLogRollOnDatanodeDeath test failure
Date Thu, 19 Dec 2013 23:38:07 GMT

Enis Soztutar commented on HBASE-10142:
---------------------------------------

This test fails much more frequently on the windows boxes on azure, because of the timing
on 0.96. Let me apply the patch there to see whether it improves the stability.

> 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 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.
