--------------------------------
Thanks for your reply very much!
In fact we created a desktop application which is implemented by eclipse rcp.
In our tools we need to connect to HDFS with kerberos. I will explain what's
the problem we face and how to reproduce it now. First we get the kerberos
ticket with "kinit" by kfw in windows system, second start our tool, it's ok we
can connect to HDFS successfully. But if the ticket is expired and we
regenerate a new one it will not be updated in our tool means we cannot connect
to HDFS although there is a available ticket . we have to restart our tool to
make it work.
> Login with kerberos should always set refreshKrb5Config to true

> When logined with kerberos by "kinit" way, it never refreshes the kerberos
> configurations. It is really often needed to be refreshed same as "keytab"
> way(The bug of "keytab" has been fixed by HADOOP-6947).
