------------------------------------------
Summary: Incorrect ATS metric request for non-HDP stack with
version 2.1
Key: AMBARI-7023
URL: https://issues.apache.org/jira/browse/AMBARI-7023
Project: Ambari
Issue Type: Bug
Affects Versions: 1.6.1
Reporter: Alexander Denissov
Priority: Critical
Define a non-HDP stack based on hadoop 2.2, such as PHD 2.1.0 with HDFS+YARN+ZK
services.
After cluster deployment when a user presses "Complete" and UI tries to
navigate to dashboard, a "Server Error" popup comes up with the message and the
UI is stuck on loading bar of
http://c6401.ambari.apache.org:8080/#/main/dashboard/metrics:
The popup has the following error message:
500 status code received on GET method for API:
/api/v1/clusters/test/components/?ServiceComponentInfo/component_name=APP_TIMELINE_SERVER|ServiceComponentInfo/component_name=JOURNALNODE|ServiceComponentInfo/category=MASTER&fields=ServiceComponentInfo/Version,ServiceComponentInfo/StartTime,ServiceComponentInfo/HeapMemoryUsed,ServiceComponentInfo/HeapMemoryMax,ServiceComponentInfo/service_name,host_components/HostRoles/host_name,host_components/HostRoles/state,host_components/HostRoles/maintenance_state,host_components/HostRoles/stale_configs,host_components/metrics/jvm/memHeapUsedM,host_components/metrics/jvm/HeapMemoryMax,host_components/metrics/jvm/HeapMemoryUsed,host_components/metrics/jvm/memHeapCommittedM,host_components/metrics/mapred/jobtracker/trackers_decommissioned,host_components/metrics/cpu/cpu_wio,host_components/metrics/rpc/RpcQueueTime_avg_time,host_components/metrics/dfs/FSNamesystem/*,host_components/metrics/dfs/namenode/Version,host_components/metrics/dfs/namenode/DecomNodes,host_components/metrics/dfs/namenode/TotalFiles,host_components/metrics/dfs/namenode/UpgradeFinalized,host_components/metrics/dfs/namenode/Safemode,host_components/metrics/runtime/StartTime,host_components/metrics/yarn/Queue,ServiceComponentInfo/rm_metrics/cluster/activeNMcount,ServiceComponentInfo/rm_metrics/cluster/unhealthyNMcount,ServiceComponentInfo/rm_metrics/cluster/rebootedNMcount,ServiceComponentInfo/rm_metrics/cluster/decommissionedNMcount&minimal_response=true
Error message: org.apache.ambari.server.controller.spi.SystemException: An
internal system exception occurred: Could not find service for component,
componentName=APP_TIMELINE_SERVER, clusterName=test, stackInfo=PHD-2.1.0
The problem, I believe is in
ambari-web/app/controllers/global/update_controller.js lines:
isATSInstalled =
App.cache['services'].mapProperty('ServiceInfo.service_name').contains('YARN')
&& App.get('isHadoop21Stack'),
flumeHandlerParam = isFlumeInstalled ?
'ServiceComponentInfo/component_name=FLUME_HANDLER|' : '',
atsHandlerParam = isATSInstalled ?
'ServiceComponentInfo/component_name=APP_TIMELINE_SERVER|' : '',
and ambari-web/app/app.js lines:
isHadoop21Stack: function () {
return (stringUtils.compareVersions(this.get('currentStackVersionNumber'),
"2.1") === 1 ||
stringUtils.compareVersions(this.get('currentStackVersionNumber'), "2.1")
=== 0)
}.property('currentStackVersionNumber'),
Since the stack version number is 2.1 and YARN is installed, the UI assumes the
stack is Hadoop 2.4 compatible (as is the case with HDP), which is not the case
with non-HDP stacks.
