Alexander Kolbasov commented on SENTRY-1964:
--------------------------------------------
I think NameNode should apply ACLs recursively to all subdirectories. This
should address this problem.
> HDFS sync does not need partition locations (usually)

> Right now, sentry saves partition info from HMS and send it to HDFS. HDFS
> only needs database and table info, and does not need partition info for ACL
> unless the partion location is not sharing the same prefix of its table.
> The partition data amount is huge, and causes performance issue. We can
> optimize it by not saving and not sending partition info if it shares the
> same path of its table.
