Sean Busbey updated ACCUMULO-2485:
----------------------------------
Attachment: ACCUMULO-2485-tserver.log
I was going to include the GC log, but browsing it looks like the GC doesn't
handle deletes for the root tablet. (from discussing with [~mdrob] I think this
is expected).
root_tablet directory in HDFS during failure:
{noformat}
-bash-4.1$ hadoop dfs -ls '/accumulo/tables/!0/root_tablet'

and after recovery:
{noformat}
-bash-4.1$ hadoop dfs -ls '/accumulo/tables/!0/root_tablet'
Found 2 items
-rw-r--r-- 5 accumulo accumulo 589 2014-03-17 07:52

/accumulo/tables/!0/root_tablet/A000002q.rf
{noformat}
I presume leaving the now defunct A0000001.rf file around won't harm anything.

> URL: https://issues.apache.org/jira/browse/ACCUMULO-2485
> Project: Accumulo
> Issue Type: Bug
> Affects Versions: 1.4.5
> Environment: 1.4.5-SNAPSHOT on 6faac42, Hadoop 1 via CDH3u6
> Reporter: Sean Busbey
> Labels: 14_qa_bug
> Fix For: 1.4.6

> Attachments: ACCUMULO-2485-tserver.log

>
> While setting up a test cluster, I mistakenly left out a home directory for
> the Accumulo user on a cluster set up with HDFS Trash enabled.
> After successfully writing out the new file for a MajC on the root tablet,
> some part of the cleanup of old files failed when moving to Trash didn't
> work. The result was that the tablet still listed one of the original files,
> but that file was no longer in HDFS.
> All future MajCs failed with file not found. Attaching representative log
> sample.
> I don't know if this impacts future versions.
> Workaround: ACCUMULO-1219 (copied the result of the initial MajC to the files
> named as its source)
