Review request for Ambari, Emil Anca, John Speidel, Robert Nettleton, and
Vitalyi Brodetskyi.
Bugs: AMBARI-9739
https://issues.apache.org/jira/browse/AMBARI-9739
Repository: ambari
Description
-------
1. Installed cluster on three hosts c6401, c6402, c6403
2. using oracle jdk 1.7, put JCE in place on all hosts
3. ambari-agent stop on c6403 (which just has DN, ZK and NM)
4. Enable kerberos, which means c6403 does not get keytabs
5. ambari-agent start on c6403
6. go to regen keytabs. Clicked to only do missing. c6403 does not get keytabs.
7. go to regen keytabs. just left the default which should do all. No hosts get
the keytabs.
What I found is since the Kerberos client didn't get installed on c6403, the
"Set keytab kerberos client" command is "Host Role in invalid state". I went to
that host, and did install clients from the UI to get the kerberos client
installed. Once that happened, I could then regen keytabs.
The main issue: Regen only works if all hosts can regen. Once c6403 did not
have a client, and Host Role in invalid state, it didn't do keytabs for any
other hosts.
This occurs because the Kerberos Client is in the INIT state on one or more
hosts. Filtering out hosts where the Kerberos Client is not in the INSTALLED
state, solves this issue.
