-----------------------------------
Summary: Ambari API does not return HDFS RPC metrics based on ports
Key: AMBARI-15606
URL: https://issues.apache.org/jira/browse/AMBARI-15606
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.2.0
Reporter: Dmytro Sen
Assignee: Dmytro Sen
Priority: Critical
Fix For: 2.2.2
ISSUE: Ambari API does not return HDFS RPC metrics based on ports (Example 8020
and 8040)
When creating Ambari Widget we don't see an option to monitor by port. Hence
the monitoring of Random port or aggregate doesn't give correct information
After the patch, ambari automatically replaces port number with the
corresponding suffix
client for the port specified in hdfs-site/dfs.namenode.rpc-address
datanode for the port specified in hdfs-site/dfs.namenode.servicerpc-address
healthcheck for the port specified in
hdfs-site/dfs.namenode.lifeline.rpc-address
