Sergey Shelukhin updated HIVE-11675:
------------------------------------
Description:
Need to take a look at the best flow. It won't be much different if we do
filtering metastore call for each partition. So perhaps we'd need the custom
sync point/batching after all.
Or we can make it opportunistic and not fetch any footers unless it can be
pushed down to metastore or fetched from local cache, that way the only slow
threaded op is directory listings
NO PRECOMMIT TESTS
