Project: Apache Drill

DROP TABLE hangs. Table was created using CTAS and the input to CTAS was a directory that had 2000 JSON files.
There is no Exception or error message on sqlline prompt nor in drillbit.log
Drill 1.4.0, git commitID: 32b85160
hadoop fs -ls /tmp shows that the directory exists (at the time when DROP TABLE was hung)
drwxr-xr-x - mapr mapr 10550677 2016-01-05 12:14 /tmp/tblMD332_wp
