      Description

      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:

      2013-08-14 11:54:27,246 [master.Master] ERROR: Unable merge metadata table records
      org.apache.accumulo.core.client.AccumuloException: java.io.IOException: Could not find file /20//c-00000000 in [hdfs://localhost:9000/accumulo/tables]

      Caused by: java.io.IOException: Could not find file /20//c-00000000 in [hdfs://localhost:9000/accumulo/tables]

              ... 2 more
      

      And the metadata table had c-00000000 listed here:

      root@802 !METADATA> grep c-00000
      20;00b581d7479230dd srv:dir []    /c-00000000
      20< srv:dir []    /c-00000001
      

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

          This is the same issue I saw in 1745, which got fixed by SOMETHING else.
