-----------------------------------------------------------
There are some static fields, such like
[authenticationMethod|https://github.com/apache/hadoop/blob/1b5c6b3a3b90c6e396e00e991b49d170eb2dac55/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/UserGroupInformation.java#L210]
in UGI. So the race still exists even they are different objects.

> Currently, to access kerberos-enabled Hive cluster, users are expected to add
