Subject [jira] [Commented] (HDFS-8772) fix TestStandbyIsHot#testDatanodeRestarts which occasionally fails
Date Wed, 05 Aug 2015 01:25:05 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8772?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14654641#comment-14654641
] 

Andrew Wang commented on HDFS-8772:
-----------------------------------

LGTM, just one q, should we bump up the waitFor to be less aggressive like 30s, and the overall
test timeout from 60s to 120s? Test boxes can be overloaded at times and run slowly, so I'd
like some more safety to avoid flakiness.
