Prasanth Jayachandran commented on HIVE-20707:
----------------------------------------------
[~jcamachorodriguez] This patch brings in breaking changes mostly for external
tables (auto partition discovery is enabled by default). That's why did not
backport the patch to branch-3. I am guessing the fixes are primarily related
to catalog name missing in metastore APIs?. If that's the case we could pick
only the changes to ObjectStore.java, NonCatCallsWithCatalog.java which are
pretty small. What do you think?

> 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.
