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

             Summary: Fragment error on TPCH Scale Factor 30 on a query that completed successfully
previously
                 Key: DRILL-2767
                 URL: https://issues.apache.org/jira/browse/DRILL-2767
             Project: Apache Drill
          Issue Type: Bug
         Environment: AWS EMR cluster of three m1.xlarge nodes
            Reporter: Alexander Zarei


The following sequence led to the error:

Executed the query 
bq. SELECT * FROM `realhive`.`tpch_text_30`.`lineitem`

and it took about 43 minutes to execute successfully. 

After ward I ran the query 
bq. SELECT * FROM `realhive`.`tpch_text_2`.`lineitem`
for 6 times to find and optimization valued for the ODBC driver. 

After ward, I submitted the very the first query again
bq. SELECT * FROM `realhive`.`tpch_text_30`.`lineitem`
 
and the Drill Cluster returned a fragment error.

Log files for the Drill Bits on the master node as well as the core nodes of the cluster are
attached.

Also the connection through the ODBC on Linux 32 bit was "Direct" to the drillbit on the master
node of the Hadoop cluster.
