Subject [jira] [Created] (AMBARI-12313) Service config pages load extremely slowly (especially on big clusters)
Date Tue, 07 Jul 2015 13:44:05 GMT
Andrii Tkach created AMBARI-12313:
-------------------------------------

             Summary: Service config pages load extremely slowly (especially on big clusters)
                 Key: AMBARI-12313
                 URL: https://issues.apache.org/jira/browse/AMBARI-12313
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.1.0
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
            Priority: Critical
             Fix For: 2.1.0


The following load time of the service config pages were observed on a 800+ node cluster:

HDFS: 36s
MAPREDUCE2: 32s
YARN: 35s
HIVE: 32s
HBASE: 30s

Ambari Web makes a number of API calls, but majority of the time is spent on UI-side processing.
 We need to see what we can optimize.
