@Shab no, those warn messages are not related. Did you try setting 'hive.metastore.client.socket.timeout' value to, 5 mins, under the "Service Monitor Client Config Overrides" in Hive configuration? We can completely disable Hive metastore canary, but I won't advise that. if Hive is working as expected, we could safely ignore these canary warnings, however, try setting the aforementioned socket timeout parameter, and that could help the canary tests perform without fail. If you use Sentry in your cluster, sometimes it blocks HMS, which in turn affects Metastore Canary. You could add the following property to overcome that. Navigate to Cloudera Manager > Hive > Configuration > "Hive Metastore Server Advanced Configuration Snippet (Safety Valve) for hive-site.xml" > add the following:
<property>
<name>hive.metastore.event.listeners</name>
<description>This will stop HMS blocking by Sentry</description>
<value></value>
</property>
