------------------------------------
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.
