Yes Sid, Even I suspected the Postgres corruption.
I tried the API provided by Yasaku. I got 500 Internal error message
mentioned below :
HTTP/1.1 500 Internal Exception: org.postgresql.util.PSQLException:

I can notice a specific key, which is highlighter in red. Does deleting
this solve the problem ?
I am not able to take a dump of existing databases as I don't know the
username and password of postgre.

username, password and database name that
Ambari uses ?
I suspect the user is posgres, which is the default user name. If I hard
reset the postgres which is mentioned in the this link, will ambari face
problem ? Which is the configuration file Ambari uses to store postgres
username and password?

Suraj,
Here's the API call that Sid mentioned for restoring key_value_store data:
curl -i -u admin:admin -H "X-Requested-By: ambari" -X POST -d '{
"CLUSTER_CURRENT_STATUS": "{\"clusterState\":\"CLUSTER_STARTED_5\"}"
}' http://localhost:8080/api/v1/persist
Hopefully this helps.

Hi Suraj,
Found a similar thread on postgres forum,
http://postgresql.1045698.n5.nabble.com/select-table-indicate-missing-chunk-number-0-for-toast-value-96635-in-pg-toast-2619-td5682176.html
The cleanup commands at the end of the topic seem worth a try.
Note: If key_value_store has corrupt data it can be deleted without
affection state of the system, there is a API call to do it, Yusaku can
probably help you get the API call for it.
1. Backup the database as it is.
2. I would try the API call and see if everything recovers.
3. Run the analyze command and re index on pg_statistic.

I think this suggests that your Postgres DB is corrupt.

Jeff,
I tried restarting both ambari-server and postgresql. Still the error
exist.
I have attached a part of the log file(log after ambari-server restart)
so
it might help to pin point the issue.
I could see following line before the Exception :

Hi,
I have a 3 node cluster with HA enabled via Ambari. Accidentally the

supply to all the nodes was disrupted. After the power was restored,
the 3

error
pops up Error in retrieving web client state from ambari server.(After
entering username and password)
It doesn't show the cluster dashboard which was showing before. Instead
it
shows "Cluster Install Wizard" to setup a new cluster. How can I
recover
from the error? I do not want to restart the installation process
Below is the error I found in /var/log/ambari-server/ambari-server.log

I found an email archive at

But I need suggestions on recovering but not starting the installation
