Dear,

I am trying to install replica by "ipa-replica-install replica-info-namenode2.hadoop.gxdwdc.gpg" but it failed,

ipa-replica-install replica-info-namenode2.hadoop.gxdwdc.gpg

...

The host namenode2.hadoop.gxdwdc already exists on the master server.

You should remove it before procedding:

% ipa host-del namenode2.hadoop.gxdwdc

Then I ran "ipa -host-del namenode2.hadoop.gxdwdc" but it still failed,

[root@namenode2 ~] ipa host-del namenode2.hadoop.gxdwdc

ipa: ERROR: did not receive Kerberos credentials

I thought i need to run "kinit" first, than I ran "kinit admin", it still failed,

[root@namenode2 ~] kinit admin

kinit: Configuration file does not sepcify default realm when parsing name admin

can anyone inform me how can i overcome this issue?

Thanks ahead.
