Subject [jira] [Updated] (HIVE-13006) LLAP: add finer-grained classloaders as an option to be able to block the usage of removed UDFs
Date Thu, 04 Feb 2016 23:52:39 GMT

     [ https://issues.apache.org/jira/browse/HIVE-13006?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sergey Shelukhin updated HIVE-13006:
------------------------------------
    Description: Right now we add an epic global classloader for executors via a thread factory,
so once added, UDFs cannot really be removed until restart. Changing the classloader for threadpool
threads might not be possible, so we'd need to make executor threads (or the threadpool) custom.
