HIVE-4226. Fixing some non-threadsafe code in hive
There is some code in Hive that is not threadsafe. These usually bubble up as
problems in Hive Server. This JIRA tracks fixing (hopefully, all) of these
issues.
Some context: we've implemented a multi-tenant (multiple dbs), multi-threaded
hive server at Qubole (QHS) which is running in production for a couple of
months now. As part of this effort, we've fixed a number of instances of
non-threadsafe code. I'm looking to contribute this back to the community.
Note that there is no new functionality here - just some better hygiene. If
there are any stress tests that have revealed hive server bugs in the past, it
will be great if they can be added to the jira.
Also, this is my first attempt at contributing to Apache, so please forgive any
mistakes.
