[jira] [Created] (HADOOP-13066) UserGroupInformation.loginWithKerberos/getLoginUser is not thread-safe

Sergey Shelukhin created HADOOP-13066:
-----------------------------------------

             Summary: UserGroupInformation.loginWithKerberos/getLoginUser is not thread-safe
                 Key: HADOOP-13066
                 URL: https://issues.apache.org/jira/browse/HADOOP-13066
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Sergey Shelukhin


When calling loginFromKerberos, a static variable is set up with the result. If someone logs in as a different user from a different thread, the call to getLoginUser will not return the correct UGI.
