Vaibhav Gumashta commented on HIVE-10895:
-----------------------------------------
[~aihuaxu] Thanks for the comments on rb. As you have also identified, there
are some issues with v1 patch (I re-read the Query.close API to figure that
calling close aggressively will cause losing the iterators). I'll upload a new
patch shortly - we need some way to close the query object other than in places
which you plan to do in HIVE-11021.
> ObjectStore does not close Query objects in some calls, causing a potential
> leak in some metastore db resources
