Verify Kudu Status After Migration

This page describes how to verify the health of your Kudu cluster after a master migration. It covers checking master roles in the Web UI, running ksck to confirm cluster integrity and validate Kudu service status in Ambari.

Check Health with the Web UI

1. Access each master’s web interface at:

http://<hostname>>:8051/masters

2. Confirm that:
   1. One master is listed as LEADER.
   2. All other masters are listed as FOLLOWERS.

Run a Cluster Health Check

Use the Kudu system check (ksck) to validate cluster integrity:

kudu cluster ksck <comma separated updated master list>

Verify Service Status in Ambari

In the Ambari dashboard, ensure all Kudu services display a Healthy status.
