Thank you Ravi.

HA Zookeeper Connection State: Auto Failover is not enabled, after enabling this it worked.

It looks like you have issues with your Resource Manager1 and your app is trying to switch over to Rresource Manager2. You can take a look at RM1 logs to see what the error is. It is either down or not responding on 8032 on time.
