Can you file a JIRA?
The lines are
boolean doAsEnabled =
conf.getBoolVar(HiveConf.ConfVars.HIVE_SERVER2_ENABLE_DOAS);
// either variables will never be null because a default value is
returned in case of absence
if (doAsEnabled !=
session.getConf().getBoolVar(HiveConf.ConfVars.HIVE_SERVER2_ENABLE_DOAS)) {
session is checked for null so somehow session.getConf() is probably null.
