Subject [jira] [Commented] (SQOOP-1748) Sqoop2: Client throws NPE when misconfigured for Kerberos
Date Wed, 26 Nov 2014 01:59:13 GMT

    [ https://issues.apache.org/jira/browse/SQOOP-1748?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14225591#comment-14225591
] 

Richard commented on SQOOP-1748:
--------------------------------

[~vinothchandar], thanks for your clarification.
{code}
1) I see that the server defaults to SimpleAuth which (from my little understanding) is just
based on username. Any idea why the client still fails trying to kinit?
What I was trying to report was : my server was down. I usually except a ConnectException.
But I got the kinit one I pasted above, which had me debugging kerberos for a while.
{code}
>From my point of view, the error message of Kerberos should not happen if simple auth
is used by default (no config modification is needed). So I am wondering what are the detail
steps you did, and I am trying to reproduce and debug it. Maybe there is something wrong on
this feature.
{code}
2) My 2c : Setting up kerberos properly (i.e kinit successfully) to just play with sqoop2,
might be a big bar.. 
This was an independent remark on not requiring kinit to be mandatory, for "quickstart" or
development, based on the comments before.
{code}
Thanks for your suggestion. The document is under development (SQOOP-1755). I will finish
it soon.
