-----------------------------
Summary: Drill C++ Client crashes on multiple
SaslAuthenticatorImpl Destruction due to communication error
Key: DRILL-7035
URL: https://issues.apache.org/jira/browse/DRILL-7035
Project: Apache Drill
Issue Type: Bug
Components: Client - C++
Reporter: Rob Wu
[~debraj92] found that when under some circumstance the SaslAuthenticatorImpl's
sasl_dispose() function will crash out at destruction. The incident seems to be
random and only when certain authentication and encryption combinations are
used during connection.
After digging a little deeper, I found that when BOOST communication error
occurs, the shutdownSocket (eventually triggering sasl_dispose()) could be
called from various threads resulting in a race condition of freeing the
handle. This can be reproduced with the querysubmitter.
[~debraj92] will be adding a patch to resolve this incident.
