Thanks for the suggestion jss.
But it could'nt solved the issue completely.
I have moved those files into temp directory and again tried to start the server but, now it given another error as
ERROR: Exiting with exit code -1.
REASON: Ambari Server java process died with exitcode 255. Check /var/log/ambari-server/ambari-server.out for more information.
when i checked into the logs, there i have found that the current version db is not comapatable with the server.
then i have tried these steps
wget -O /etc/yum.repos.d/ambari.repo http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.2.1.0/ambari.repo
yum install ambari-server -y
ambari-server setup -y
wget -O /etc/yum.repos.d/ambari.repo http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.2.1.1/ambari.repo
yum upgrade ambari-server -y
ambari-server upgrade
ambari-server start
when i run these commands after that ambari server did started but here is the amazing this has happened.
actually, i removed the ambari completely and trying to reinstall it.
when i completed all the above steps, and when i entered into the ambari ui, it is again pointing to the same host which i have removed previously. I was just shocked by seeing that with heartbeat lost.
then i realised that ambari agent is not at installed,
then i installed ambari agent and started it .
yum -y install ambari-agent
ambari-agent start
then,when i tried to start the services it didnt worked.
i checked in command prompt that, is these all serivecs still exist or not ?, by entering zookeeper . but that command is not found, because service is not installed in my host.
Then i started to remove the services from the host which is present in a dead mode,using these commands.
curl
-u admin:admin -H “X-Requested-By: Ambari” -X DELETE http://localhost:8080/api/v1/clusters/hostname/services/servicename
but it didnt worked, I got a error msg as
message" : "CSRF protection is turned on. X-Requested-By HTTP header is required."
then i have edited the ambari-server.properties file and added these lines into that
vi /etc/ambari-server/conf/ambari.properties
api.csrfPrevention.enabled=false
ambari-server restart
then again i have retried it, at this time it did worked.
But when i tried to remove hive, it didnt,because mysql is running in my machine.
when i tried this command it did worked.
curl -u admin:admin -X DELETE -H 'X-Requested-By:admin' http://localhost:8080/api/v1/clusters/mycluster/hosts/host/host_components/MYSQL_SERVER
then, when i tried to add the services starting with zookeeper,again,
it given me error like
"resource_management.core.exceptions.Fail: Applying
Directory['/usr/hdp/current/zookeeper-client/conf'] failed, looped
symbolic links found while resolving
/usr/hdp/current/zookeeper-client/con
Then i have checked the directories, i got to know that these links were pointing back to the same directories.
So, i have tried these commands to solve this issue.
rm /usr/hdp/current/zookeeper-client/conf
ln -s /etc/zookeeper/2.3.2.0-2950/0 /usr/hdp/current/zookeeper-client/conf
And it did worked.
at last i have successfully reinstalled the ambari as well as hadoop in my machine.
Thank you.
