[jira] [Created] (HADOOP-17159) Ability for forceful relogin in UserGroupInformation class

Sandeep Guggilam created HADOOP-17159:
-----------------------------------------

             Summary: Ability for forceful relogin in UserGroupInformation class
                 Key: HADOOP-17159
                 URL: https://issues.apache.org/jira/browse/HADOOP-17159
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Sandeep Guggilam


Currently we have a relogin() method in UGI which attempts to login if there is no login attempted in the last 10 minutes or configured amount of time

We should also have provision for doing a forceful relogin irrespective of the time window that the client can choose to use it if needed . Consider the below scenario:
 # SASL Server is reimaged and new keytabs are fetched with refreshing the password
 # SASL client connection to the server would fail when it tries with the cached service ticket
 # We should try to logout to clear the service tickets in cache and then try to login back in such scenarios. But since the current relogin() doesn't guarantee a login, it could cause an issue
 # A forceful relogin in this case would help after logout
