Eric Pugh resolved SOLR-8894.
-----------------------------
Resolution: Won't Do
Hadoop Auth removed in Solr 10.
> Support automatic kerberos ticket renewals in standalone Solr
> -------------------------------------------------------------
>
> Key: SOLR-8894
> URL: https://issues.apache.org/jira/browse/SOLR-8894
> Project: Solr
> Issue Type: Bug
> Reporter: Varun Thacker
> Priority: Major
>
> Currently in standalone Solr mode , tickets are not renewed automatically. So
> once a ticket expires one has to restart the solr node for it to renew the
> ticket.
> We should support automatic ticket renewals in standalone solr as we do
> currently in cloud mode.
> There is no workaround for this other than to restart Solr.
> If we manually do a kinit ( so that we can set a cron to do future kinit's )
> and then start Solr , Solr doesn't start up correctly. Steps we tried for the
> workaround:
> - Specify useKeyTab=false in the JAAS fle and then manually do a kinit and
> then start solr. So fails to start in this case and throws an error like this
> {code}
> ERROR - 2016-03-14 20:07:03.505; [ ] org.apache.solr.common.SolrException;
> null:org.apache.solr.common.SolrException: Error initializing kerberos
> authentication plugin: javax.servlet.ServletException:
> org.apache.hadoop.security.authentication.client.AuthenticationException:
> javax.security.auth.login.LoginException: No key to store
> {code}
