[jira] [Created] (DRILL-2038) C++ Client syncronous API has a concurrency issue with multiple parallel queries

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

             Summary: C++ Client syncronous API has a concurrency issue with multiple parallel queries
                 Key: DRILL-2038
                 URL: https://issues.apache.org/jira/browse/DRILL-2038
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - C++
    Affects Versions: 0.8.0
            Reporter: Parth Chandra
            Assignee: Parth Chandra
             Fix For: 0.8.0


Issuing about 30 parallel queries to the C++ client (thru the query submitter test program). Some of the queries return failure. The client application seems to get into a state where the query state on the client is running even though the server has completed the query and is not longer sending results back.

The issue appears to be related to the handling of the QUERY_COMPLETED state. The synchronous API expects that if the error object associated with the query result is nut null, the query should have failed.
