-------------------------------------
Summary: Host Component metrics always showing zero values
Key: AMBARI-1442
URL: https://issues.apache.org/jira/browse/AMBARI-1442
Project: Ambari
Issue Type: Bug
Reporter: Tom Beerbower
Assignee: Tom Beerbower
Fix For: 1.2.2
In spite of the fact that some hadoop jobs that were performed, all fields of
shuffle metrics have 0.0 values.
Used the following request to get shuffle metrics:
{code}
api/v1/clusters/clusterName/hosts/hostName/host_components/TASKTRACKER?fields=metrics/mapred/shuffleOutput
{code}
Result:
{code}
"metrics" : {
"mapred" : {
"shuffleOutput" :
{ "shuffle_success_outputs" : 0, "shuffle_handler_busy_percent" : 0,
"shuffle_output_bytes" : 0, "shuffle_failed_outputs" : 0,
"shuffle_exceptions_caught" : 0 }
}
}
{code}
