Thank you very much for the feedback and sorry for the late reply, I will
rebase the commits. Hey @belugabehr, cloud you please take another look if have
secs?
The issue can be seen in long live shared Metastore client(spark, client
pool), the unreleased queries would accumulate to seeing the OOM. The former
patch we applied to Hive version 1.2 solved it, this patch introduces
try-with-resource on the query and a sanity check on the master.
