Thejas M Nair updated HIVE-4625:
--------------------------------
Description:
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.
