Shawn Guo 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 based on which a background metastore thread can sync partitions periodically. Tables can also be specified with partition retention period. Any partition whose age exceeds the retention period will be dropped automatically.rr  (was: In current scenario, to add partitions for external tables to metastore, MSCK REPAIR command has to be executed manually.
