      Description

      Running bulk randomwalk against 1.4.5-SNAPSHOT, got this in verification:

      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)
      

      Possible reasons:

      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:

      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)
              at org.apache.accumulo.core.client.admin.TableOperationsImpl.importDirectory(TableOperations
      Impl.java:947)
              at org.apache.accumulo.server.test.randomwalk.bulk.BulkPlusOne.bulkLoadLots(BulkPlusOne.java
      :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
      

      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.
