Daniel Dai commented on HIVE-19938:
-----------------------------------

Thejas point out we need to manage hive schema separately. Otherwise db upgrade 
will update version thus hive schema upgrade will not run. So change the script 
to load data into version to avoid tez job. Also improve embedded hs2 in the 
patch to turn off acid and metastore cache.
