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.
