Subject [jira] [Commented] (HADOOP-10895) HTTP KerberosAuthenticator fallback should have a flag to disable it
Date Thu, 11 Dec 2014 01:21:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14241962#comment-14241962
] 

Robert Kanter commented on HADOOP-10895:
----------------------------------------

I've re-looked at rev 8 and it looks fine to me.  I'm going to try it out a bit in a cluster
soon.  
In the meantime, any other comments from anyone?  [~tucu00]? [~hitliuyi]?

[~yzhangal], I'm not sure the release note covers all cases.  I don't think the "ipc.client.fallback-to-simple-auth-allowed"
property covers the case of a 3rd-party program (i.e. a non-Hadoop program) using KerberosAuthenticator
directly, as it doesn't use that config.  So while this release note is fine for Hadoop components,
it doesn't look like it's accurate for non-Hadoop components.  You could just add something
about setting it programmatically.

> Per review feedback in HADOOP-10771, {{KerberosAuthenticator}} and the delegation token
version coming in with HADOOP-10771 should have a flag to disable fallback to pseudo, similarly
to the one that was introduced in Hadoop RPC client with HADOOP-9698.
