Unable to save Configurations in Ambari

[Shaik M <mu...@gmail.com>]

Hi,

I have recently started upgrade hdp 2.3 to 2.5.

As part of upgrade procedure I have upgraded Amabri  2.1.2 to 2.4.1.0
without any issues.

I have started HDP upgrade, due to some internal issues I have rollback hdp
upgrade. after rollback i am unable to changes any configuration in Ambari.
I am getting "Failure in saving service configuration" message.

Error Log "ambari-server.log"
