[jira] [Commented] (HBASE-6667) TestCatalogJanitor occasionally fails

["Jesse Yates (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-6667?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13468820#comment-13468820 ] 

Jesse Yates commented on HBASE-6667:
------------------------------------

This test hasn't been failing on trunk for the last 100+ builds and has been running under a second in every build (generally under 100ms, with some variance).  See https://builds.apache.org/job/HBase-TRUNK/3414/testReport/junit/org.apache.hadoop.hbase.master/TestCatalogJanitor/testArchiveOldRegion/history/

I'd like to move to close this as won't fix. I have no idea what went wrong with the original test - its all single threaded and a fairly simple test. It might have been some weird GC issue where the cleanup ran early or bled over from another test running cleanup. However, ran the test again 20x on trunk locally without issue.
