Lefty Leverenz commented on HIVE-5626:
--------------------------------------
*hive.metastore.try.direct.sql.ddl* needs a description in
hive-default.xml.template (or in HiveConf.java after HIVE-6037 commits).
[~sershe], if you write a release note for this jira I can make sure it gets
into the appropriate file and add it to the wiki.

> 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.
