Subject [jira] [Updated] (YARN-473) Capacity Scheduler webpage and REST API not showing correct number of pending applications
Date Wed, 13 Mar 2013 18:50:13 GMT

     [ https://issues.apache.org/jira/browse/YARN-473?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kendall Thrapp updated YARN-473:
--------------------------------

    Description: 
The Capacity Scheduler REST API (http://hadoop.apache.org/docs/r0.23.6/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html#Cluster_Scheduler_API)
is not returning the correct number of pending applications.  numPendingApplications is almost
always zero, even if there are dozens of pending apps.

In investigating this, I discovered that the Resource Manager's Scheduler webpage is also
showing an incorrect but different number of pending applications.  For example, the cluster
I'm looking at right now currently has 15 applications in the ACCEPTED state, but the Cluster
Metrics table near the top of the page says there are only 2 pending apps.  The REST API says
there are zero pending apps.
