Subject [jira] [Commented] (HIVE-12187) Release plan once a query is executed
Date Thu, 22 Oct 2015 20:13:27 GMT


Chaoyu Tang commented on HIVE-12187:

[~jxiang] The patch looks good to me, except I am not quite sure about saving the locks in
close() method. Do you know under what circumstance that there are some locks left from last
query and should be preserved? Thanks

> Some clients leave query operations open for a while so that they can retrieve the query
results later. That means the allocated memory will be kept around too. We should release
those resources not needed for query execution any more once it is executed.
