Devaraj Das updated HADOOP-6706:
--------------------------------
Attachment: 6706.bp20.patch
Attaching a patch for the Y20 branch. "Exception" is caught and a relogin is
attempted. We were debating whether to have relogin done outside the exception
block before doing a saslConnect. But even in that case, we need to be able to
handle exceptions since some other thread might be currently using the subject
credentials that we are just about to destroy (in relogin) and that thread
should retry the connection after a relogin. In any case the exception handling
is required.
> Relogin behavior for RPC clients could be improved

> Currently, the relogin in the RPC client happens on only a SaslException. But
> we have seen cases where other exceptions are thrown (like
> IllegalStateException when the client's ticket is invalid). This jira is to
> fix that behavior.
