Timothy Chen commented on YARN-473:
-----------------------------------

I'd like to look into this, but I cannot assign this bug to myself. Can someone assign this
to me or give me permissions? Thanks.

> 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.
