Ambari is unable to fetch Host Components

Ambari is not able to load service details for all the components like (Hbase,hdfs,zookeeper etc.) after upgrading Ambari from 2.1.2 to 2.4.2. The error found in ambari-server logs is,

22:43:27,505 WARN [ambari-client-thread-2495] ServletHandler:561 - Error Processing URI: /api/v1/clusters/<CLUSTER_NAME>/host_components - (java.lang.ArrayIndexOutOfBoundsException) 1

@Prabhat Singh

Can you pelase check if the following properties are set correctly? yarn.resourcemanager.webapp.https.address.XYZ with port 8090 (default)

Example:

yarn.resourcemanager.webapp.https.address = erie3.example.com:8090
yarn.resourcemanager.webapp.https.address.rm1 = erie3.example.com:8090
yarn.resourcemanager.webapp.https.address.rm2 = erie2.example.com:8090

Similarly please check the

yarn.resourcemanager.webapp.address

- Please make sure that the Port is mentioned in the address. Missing port can cause this issue.

Hi jss,

Thanks for a quick response. This is what i can see,

yarn.resourcemanager.webapp.https.address=<hostname>:8090
yarn.resourcemanager.hostname.rm1=<hostname>
yarn.resourcemanager.webapp.address.rm1=<hostname>
yarn.resourcemanager.hostname.rm2=<hostname>
yarn.resourcemanager.webapp.address=<hostname>:8088

We have two more cluster where we are running version 2.4.1.0 of Ambari. The two are working fine with above properties. Is there any major change in Ambari 2.4.2?

Please suggest.

By adding the port solves the issue.

Thanks a lot @jss
