Subject [jira] [Created] (HIVE-4226) Cleanup non-threadsafe code in Hive
Date Mon, 25 Mar 2013 10:43:16 GMT
Sivaramakrishnan Narayanan created HIVE-4226:

             Summary: Cleanup non-threadsafe code in Hive
                 Key: HIVE-4226
             Project: Hive
          Issue Type: Improvement
            Reporter: Sivaramakrishnan Narayanan

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.
