Problems with impalad 2.2.0 and CDH 5.4.4: The health of the Impala Catalog Server is bad

avatar

Hello @All,

 

we are running CDH 5.4.4 and Cloudera Manager 5.4.3 on Centos 6.4 Systems

Everything runs fine except the impala Monitoring.

The service itself is also running fine. It seems that only the monitoring of the impala daemons on all hosts and the catalogserver is not working:

 

 

The error-Messages are as follows:

 

"The Cloudera Manager Agent got an unexpected response from this role's web server. "
