Subject [jira] Updated: (HADOOP-6706) Relogin behavior for RPC clients could be improved
Date Thu, 15 Apr 2010 00:41:49 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-6706?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

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.

> 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.
