Subject Running Giraph with secure Hadoop
Date Mon, 29 Oct 2012 22:29:56 GMT
Hi

I am trying to configure Hadoop with Kerberos for running Giraph as gives
in <
https://cwiki.apache.org/confluence/display/GIRAPH/Quick+Start+-+Running+Giraph+with+Secure+Hadoop
>

I am using Ubuntu 12.04 and installed krb5-kdc and krb5-admin-server. Had
to change principals.sh to use "kinit $NORMAL_USER@$REALM" for the ticket
granting to work. I also added the passwords for all services in
the addprinc commands. When I try to start my Hadoop 1.0.3 namenode, it
gives me the following connection refused error.
