Subject Thrift server kerberos ticket refresh
Date Tue, 20 Jun 2017 11:17:18 GMT
Hi all,

I have been looking through the hbase-thrift code looking for where
the server performs renewals of kerberos tickets for the provided
principal/keytab. I cannot seem to find any trace of this?

As an example, the hadoop-common provides the class
UserGroupInformation, which exposes the method
checkTGTAndReloginFromKeytab. I can see that the ThriftServerRunner
has a handle to the class
(https://github.com/apache/hbase/blob/master/hbase-thrift/src/main/java/org/apache/hadoop/hbase/thrift/ThriftServerRunner.java#L205),
but I do not see the ticket renewal logic being called anywhere. Am I
missing something about how this works?


Thanks for the time and best regards,
Steen
