@Swagat Few things you need to check: 

1. Do you really have Kerberos enabled in the Cluster? If not you don’t need KT Renewer service. 

2. If you have Kerberos, then add Impala service and it will activate the keytab creation.

3. If you have Kerberos in healthy state as well impala in healthy state. Then try regeneration of Kerberos Credentials from CM > Settings > Kerberos Credentials page. 

 

Let me know how it goes if it still occurs send the stderr logs from window.
