Subject [jira] [Commented] (HADOOP-10895) HTTP KerberosAuthenticator fallback should have a flag to disable it
Date Mon, 03 Nov 2014 20:09:34 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14195014#comment-14195014

Yongjun Zhang commented on HADOOP-10895:
----------------------------------------

Hi @tucu,

Thanks for answering Robert's question. The fallback default introduced for HADOOP-9698 is
false:
http://mail-archives.apache.org/mod_mbox/hadoop-common-commits/201307.mbox/%3C20130730181051.B71712388900@eris.apache.org%3E
Which means, if we are going to use the same config property, the default will be false (changing
from the hardcoded default).
Do we need to introduce a different config property for this? It seems consistent to have
same default for this one and hadoop-9698.

BTW, would you please also address  my questions to you in my last comment? I tried to address
Robert's comment #4, that's what made me to move from rev3 to rev4. Sounds rev3 is close to
what you are suggesting. Thanks a lot.

> 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.
