Description

When UserGroupInformation logs in a user from the ticket cache, it spawns a thread which renews the TGT ticket before it expires (HADOOP-6656). This happens even for non-renewable tickets, which results in error messages being printed to the console.

We should only try to renew the ticket if it has the "Renewable" flag.
