Subject [jira] [Resolved] (ACCUMULO-3865) miniDFS not reinitialized on MiniAccumuloClusterImpl
Date Tue, 09 Jun 2015 17:54:03 GMT

     [ https://issues.apache.org/jira/browse/ACCUMULO-3865?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Christopher Tubbs resolved ACCUMULO-3865.
-----------------------------------------
    Resolution: Fixed

Closing with the javadoc and better exception message, since miniDFS doesn't really support
restarts.

>    Affects Versions: 1.6.0, 1.6.1, 1.6.2
>            Reporter: Josh Elser
>            Assignee: Christopher Tubbs
>             Fix For: 1.6.3, 1.7.1, 1.8.0

>          Time Spent: 0.5h
>  Remaining Estimate: 0h

> Noticed this looking at ACCUMULO-3864.
> {{stop()}} nulls the miniDFS local member, but it's only initialized in the constructor,
not {{start()}}.
> Calling {{start()}} after a {{stop()}} when {{useMiniDFS(true)}} will hang indefinitely
because the filesystem is unavailable. It will likely also NPE in certain places.
