----------------------------------------------

[~snarayanan]: Thank you very much for contributing this patch to the project. I've a question regarding the QHS. Does this build on the existing HiveServer or is this something you guys have built from scratch?

> 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.
