Review request for Ambari, Dmitro Lisnichenko, Jonathan Hurley, Nate Cole, and
Robert Levas.
Bugs: AMBARI-9627
https://issues.apache.org/jira/browse/AMBARI-9627
Repository: ambari
Description
-------
Node Manager failed to restart in a Kerberized cluster while performing a
Rolling Upgrade.
I deployed a 3-node cluster with all services from HDDFS through ZK, then
enabled Namenode HA, and kerberized the cluster.
When I performed a RU from 2.2.0.0 GA bits to 2.2.1.0-2260, I first had to
comment out an error in ZK server, and when I got to the Slaves group,
NodeManager failed. See attached log.
```
Fail: Execution of '/usr/bin/kinit -kt /etc/security/keytabs/nm.service.keytab
nm/[email protected];' returned 1. kinit: Keytab contains no suitable keys for
nm/[email protected] while getting initial credentials
```
```
[root@c6404 ~]# klist -kt /etc/security/keytabs/nm.service.keytab
Keytab name: FILE:/etc/security/keytabs/nm.service.keytab

```
This means that params.py is probably missing to replace _HOST with the value.

Testing (updated)
-------
Deployed a 3-node cluster with HDFS, YARN, ..., ZK, then added Namenode HA, and
kerberized the cluster. After performing a RU, I verified that the fix for
NodeManager worked.
Unit tests passed in ABO.
