The file system is probably being closed by the really annoying shutdown hook.

You may need to trace through the METADATA table updates by decoding write-ahead logs to find out what happened.  It can take days.

>             Project: Accumulo
>          Issue Type: Bug
>          Components: master, test
>    Affects Versions: 1.4.4
>            Reporter: Bill Havanki
>              Labels: import, randomwalk, test

> Running bulk randomwalk against 1.4.5-SNAPSHOT, got this in verification:
> {noformat}
> Caused by: java.lang.Exception: Bad key at r00000 cf:000 [] 1394658887772 false 1
>         at org.apache.accumulo.server.test.randomwalk.bulk.Verify.visit(Verify.java:65)
> {noformat}
> Possible reasons:
> * ACCUMULO-2110, not backported to 1.4 or 1.5
> * master agitation
> I see in the logs three internal errors from imports that failed due to the masters being restarted. The failure timing is around 5 seconds after the masters restart. Example:
> {noformat}
> 12 14:10:17,580 [bulk.BulkMinusOne] ERROR: org.apache.accumulo.core.client.AccumuloException: Intern
> al error processing waitForTableOperation
> org.apache.accumulo.core.client.AccumuloException: Internal error processing waitForTableOperation
>         at org.apache.accumulo.core.client.admin.TableOperationsImpl.doTableOperation(TableOperation
> sImpl.java:290)
>         at org.apache.accumulo.core.client.admin.TableOperationsImpl.doTableOperation(TableOperation
> sImpl.java:258)

> :99)
>         at org.apache.accumulo.server.test.randomwalk.bulk.BulkMinusOne.runLater(BulkMinusOne.java:2
> 9)
> ...
> Caused by: org.apache.thrift.TApplicationException: Internal error processing waitForTableOperation
> {noformat}
> Two BulkMinusOne and one BulkPlusOne failed, which may be why the offending row was at value 1.
> The {{TableOperationsImpl.waitForTableOperation}} method does not catch {{TApplicationException}}, so the imports fail.
> I see lots of previous work on this sort of error in ACCUMULO-334 and ACCUMULO-2110. If anyone has troubleshooting tips I'd be happy to hear them.
