Are you running drill in embedded mode? The directory containing the drillbit.log file contains
the drillbit.out file too. There might be a JVM core dump in the /tmp directory.

Usually "Received shutdown request” message means that’s the drillbit ran out of memory.
Given that you mentioned the query is on a large document set, this scenario is likely.
