Create per-session function registry

Details

    • Incompatible change
    • Hide
      Marked as incompatible because of a bug -

      This patch broke automatic loading of externally added permanent functions in HiveServer2. This only affects multi-HS2 setup, where only one HS2 adds the function; or functions added from Hive CLI bypassing HS2. In such cases, HS2 will not be able to run a query with the new function.

      Additionally, RELOAD FUNCTION call has been broken by this patch.
      Workaround:
      The HS2s that don't have the function need to be restarted.

    Description

      Currently the function registry is shared resource and could be overrided by other users when using HiveServer. If per-session function registry is provided, this situation could be prevented.
