Siying Dong commented on HIVE-1517:
-----------------------------------
The concurrency issue seems to be that in the codes of acquiring locks, we
always lock current database but when we locking every table or partition, we
don't lock database of them, so that it breaks when we reference table from
other databases. When I lock database for every table/partitions, the test
passes.
Namit, do you think I should remove the codes to lock the current database? Is
there a reason we always lock current database?
