---------------------------------------

             Summary: "File does not exist" error during client ingest with agitation
                 Key: ACCUMULO-2333
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2333
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.5.0
            Reporter: Luke Brassard


While running the agitator during a client ingest test, encountered a "File does not exist"
error that stuck in the Table Problems section of the monitor page. While it appears that
no data was lost, it is strange that the error surfaced and then seemed to right itself shortly
thereafter. (though not updating the Table Problems section)

Here is the stacktrace from the Monitor:
