----------------------------------------
Summary: Kerberos: start + test fails on NodeManager due to
ambari-qa usercache
Key: AMBARI-9372
URL: https://issues.apache.org/jira/browse/AMBARI-9372
Project: Ambari
Issue Type: Bug
Components: security
Affects Versions: 2.0.0
Reporter: Erik Bergenholtz
Fix For: 2.0.0
This is on a two-node cluster. The NodeManager on one of the nodes (c6402)
starts just fine. It's this second node where the nodemanager fails (c6403)
with the following:
Build #398
[root@c6402 keytabs]# ambari-server --hash
c0167f89d7c293f39f62fbf9df0b6640bde25b51
[root@c6402 keytabs]#
NodeManager fails to start, with this error.
