LogSearch Does not start post Ambari upgrade

[#1]

I have LogSearch installed on cluster with Ambari 2.4.2.0

upgrade Ambari to 2.5.0

Log Search fails to start

{code}

@svelpula I recall hitting this issue after ambari Upgrade. Keytab infra-solr was not present on the host before the upgrade.

Regenerating keytabs worked for me.

You can do that from the ambari UI. Under Admin tab -> Kerberos , there is a button to regenerate keytabs

Before Ambari 2.5.0, solr keytab was not on logsearch host, hence it is expected that user re-generates keytabs post Ambari upgrade before restarting LogSearch. Ambari has an option Regenerate Keytabs under Admin--> Kerberos to do the same
