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 > -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
