John Vines resolved ACCUMULO-1653.
----------------------------------
Resolution: Duplicate
This is the same issue I saw in 1745, which got fixed by SOMETHING else.
> Unable to merge during RandomWalk

> I was running RandomWalk and ran into an issue where one of my walkers got
> stuck doing a merge (on table id=20). The only related error that showed up
> was that a file in HDFS couldn't be found (and continues to not be found, it
> keeps checking regularly) while trying to merge the metadata records. Here's
> the error:
> {noformat}
> 2013-08-14 11:54:27,246 [master.Master] ERROR: Unable merge metadata table
> records

> I was testing my table namespaces code but this seemed like an unrelated
> issue.
