> In kerberos secure mode, with doas enabled, Hive server2 tries to get delegation token
from metastore even if the metastore is being used in embedded mode. 
> To avoid failure in that case, it uses catch block for UnsupportedOperationException
thrown that does nothing. But this leads to an error being logged  by lower levels and can
mislead users into thinking that there is a problem.
> It should check if delegation token mode is supported with current configuration before
calling the function.
