-----------------------------------
Summary: Initial concurrenct query fails
Key: DRILL-2629
URL: https://issues.apache.org/jira/browse/DRILL-2629
Project: Apache Drill
Issue Type: Bug
Affects Versions: 0.8.0
Environment: RHEL 6.4
Reporter: Kunal Khatua
Fix For: 0.9.0
When launching concurrently queries on multiple connections (1 query per
connection) for the 1st time, some queries (which otherwise run without issue)
fail with IndexOutOfBoundsException
Here is a sample case where 2 threads (PipSQuawkling.java) executed 2 different
queries on separate SQL Connection objects.
