Subject [jira] [Commented] (ACCUMULO-1292) Tablet constructor can hang on vfs classloader, preventing tablets from loading
Date Thu, 22 Jan 2015 19:54:34 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1292?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14288111#comment-14288111
] 

Josh Elser commented on ACCUMULO-1292:
--------------------------------------

{{DaemonFactory}} is marked:

{code}
@InterfaceAudience.LimitedPrivate({"HDFS", "MapReduce"})
@InterfaceStability.Unstable
{code}

I'd prefer to see the {{Runnable}} {{refresher}} be made a {{Daemon}}. The possible Hadoop
instability isn't worth it when an alternative is so simple, IMO.

Also, any comments on actually testing these changes?  It would be very nice to have something
in place to verify correct functionality.

Aside from that, I think it looks OK.
