I am trying to upgrade RHEL OS from 6 to 7.
As oart of it, I have migrated Ambari and Kerberos to RHEL 7 server and trying to use recover Host option in Ambari.
It only pefforming kerberos lretaed work in prearing operations and not recovering any existing service.
Belwo is the hostcomponentstate in Ambari.
| 2 | 2 | NAMENODE | 22.214.171.124-8 | INSTALLED | 2 | HDFS | NONE | SECURED_KERBEROS
This is very important to migrate OS from RHEl-6 to 7
Can anyone help to resolve the issue?
Its very urgent as OS upgrade is waiting on it.
Venkata how did you resolve this, i am looking forward to doing an OS upgrade.
Though i know Recover Host does re-installation , i am not sure if an OS upgrade needs reinstallation.
