André Kelpe updated HIVE-12426:
-------------------------------
Description: SessionState.get().getHiveOperation() is supposed to allow
easy access to the current kind of operation. The information however is
incorrect in the HiveServer2 case, since the setting of the value is happening
in a different thread than the code than the actual user session is in. Since
this is a ThreadLocal there is no way to retrieve the correct value, if it is
set by a different thread. (was: SessionState.get().getHiveOperation() is
