Sergey Shelukhin updated HIVE-5626:
-----------------------------------

    Attachment: HIVE-5626.01.patch

Fix the issue where tx-es are rolled back where they should not be. Refactor 
all of this common code into a helper class.
It could be much cleaner if there were first-class functions in Java so I could 
pass them to it...

> enable metastore direct SQL for drop/similar queries

> Metastore direct SQL is currently disabled for any queries running inside 
> external transaction (i.e. all modification queries, like dropping stuff).
> This was done to keep the strictly performance-optimization behavior when 
> using Postgres, which unlike other RDBMS-es fails the tx on any syntax error; 
> so, if direct SQL is broken there's no way to fall back. So, it is disabled 
> for these cases.
> It is not as important because drop commands are rare, but we might want to 
> address that. Either by some config setting or by making it work on 
> non-postgres DBs.
