Prasanth Jayachandran updated HIVE-20707:
-----------------------------------------
Description: In current scenario, to add partitions for external tables to
metastore, MSCK REPAIR command has to be executed manually. To avoid this
manual step, external tables can be specified a table property (for retention
policy) based on which a background metastore thread can add/drop/sync
partitions periodically. The retention policy can be generically extended to
managed tables as well (provided appropriate locks are obtained for adding and
dropping partitions) (was: In current scenario, to add partitions for external
tables to metastore, MSCK REPAIR command has to be executed manually. To avoid
