> HIVE-20172 solved an issue where HMS was running the compaction worker, and
> StatUpdater thus ran in the very same JVM causing kerberos issues while
> connecting to "itself". The fix was to update HMS URI setting to empty
> string. This way HMS wouldn't have to go around itself to connect to itself :)
> But.. this is not correct anymore, as Hive doesn't support running the
> compaction worker on HMS side anymore, but only on HS2. So in any case this
> code part ends up executed in HS2, where an embedded HMS will be created due
> to this empty string URIs config, and eventually will open connections
> directly to HMS backend DB.
> We need to remove this setting as it was fixing something that is not
> relevant anymore.
