Re: Ranger Admin is failing to start

We checked this over webex on case yesterday. Issue was with structured-out-*.json. Ambari agent log indicated that the file that it was looking for is structured-out-<>.json. /var/lib/ambari-agent/data/structured-out-status.json to backup and restarted agent. This fixed this issue.

If I execute the command directly from the CLI,

/usr/java/default/bin/java -cp /usr/lib/ambari-agent/DBConnectionVerification.jar:/usr/share/java/postgresql.jar:/usr/hdp/current/ranger-admin/ews/webapp/WEB-INF/lib/* org.apache.ambari.server.DBConnectionVerification 'jdbc:postgresql://hostranger.hdp.com:5432/rangerdb' rangerdba [PROTECTED] org.postgresql.Driver

Its working fine and we are getting the o/p -

Connected to DB Successful

Re: Ranger Admin is failing to start

What ranger and ambari version do you have?

@Jonas Straub We are using Ranger 0.5.0.2.3 and Ambari 2.1

Re: Ranger Admin is failing to start

Have you checked and updated postgresql.conf and pg_hba.conf to allow user rangerdba to access rangerdb from any host in the cluster? You can find details here:

http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-...

If you change those files be sure to run "pg_ctl reload" so that changes take effect.

This issue occurred when we modified the configuration of ranger log directory.

The issue is resolved.

We took a backup of /var/lib/ambari-agent/data/structured-out-status.json and restarted Ambari Agent.

Post this, restart of Ranger Admin went fine.
