Subject [jira] [Commented] (ACCUMULO-4425) VolumeIT.testDirtyReplaceVolumes fails
Date Fri, 26 Aug 2016 22:39:21 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-4425?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15440073#comment-15440073

Christopher Tubbs commented on ACCUMULO-4425:
---------------------------------------------

It looks like when it fails, it routinely fails because there's still a CLOSED WAL still referenced.
When I wrap this check with some code to continuously retry, I get the following failure:
{code}

It looks like the {{WalStateManager}} doesn't like when the WAL state is deleted from underneath
it.
