Christopher Tubbs updated ACCUMULO-1840:
----------------------------------------
Fix Version/s: (was: 1.6.0)
> Deleted WAL still referenced in !METADATA
> -----------------------------------------
>
> Key: ACCUMULO-1840
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1840
> Project: Accumulo
> Issue Type: Bug
> Components: gc, master, tserver
> Reporter: Josh Elser
> Priority: Critical
>
> Running b0da55 locally with hadoop2.2.0.
> I wrote some data to a number of tables. Killed the tabletserver. The
> tabletserver failed to complete recovery because it ran out of memory.
> I upped the tserver's heap, and restarted it. !METADATA and !!ROOT are online
> and have all tablets assigned, but none of the other tables are coming
> online. There's a log entry for each of the tables that aren't online. Each
> of those tables have only one tablet.
