Zhihua Deng commented on HIVE-16114:
------------------------------------
the blame code snippet:
<code>
if (doAsEnabled !=
session.getConf().getBoolVar(HiveConf.ConfVars.HIVE_SERVER2_ENABLE_DOAS))
</code>
it seems that the session got from threadlocal has not been opened yet or has
been closed, So the session.getConf() is probably null.
> NullPointerException in TezSessionPoolManager when getting the session
