    Description

      Until I did an invalidate metatada, a simple

      select count(*) from scale_test
      

      would fail without any error message

      [04/Apr/2016 17:36:10 -0700] thrift_util  DEBUG    Thrift call <class 'ImpalaService.ImpalaHiveServer2Service.Client'>.GetOperationStatus returned in 24ms: TGetOperationStatusResp(status=TStatus(errorCode=None, errorMessage=None, sqlState=None, infoMessages=None, statusCode=0), operationState=5, errorMessage=None, sqlState=None, errorCode=None)
      [04/Apr/2016 17:36:10 -0700] thrift_util  DEBUG    Thrift call: <class 'ImpalaService.ImpalaHiveServer2Service.Client'>.GetOperationStatus(args=(TGetOperationStatusReq(operationHandle=TOperationHandle(hasResultSet=True, modifiedRowCount=None, operationType=0, operationId=THandleIdentifier(secret='|\x061Lz\rL\x92\xa6\xd1gkL\xbd\x95,', guid='|\x061Lz\rL\x92\xa6\xd1gkL\xbd\x95,'))),), kwargs={})
      

      On the Impalad UI there was

      Status: Error seeking to 1476395008 in file: hdfs://jennykim-1.vpc.cloudera.com:8020/user/jennykim/scale_test/scale_test.csv Error(255): Unknown error 255 
      

      and after an

      INVALIDATE METADATA
      

      the problem went away, but there is no help for the user.
