Adam Antal created YARN-10286:
---------------------------------

             Summary: PendingContainers bugs in the scheduler outputs
                 Key: YARN-10286
                 URL: https://issues.apache.org/jira/browse/YARN-10286
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 3.3.0
            Reporter: Adam Antal
            Assignee: Adam Antal


There are some problems with the  {{ws/v1/cluster/scheduler}} output of the ResourceManager:
Even though the pendingContainers field is [documented|https://hadoop.apache.org/docs/r3.2.0/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html#Cluster_Scheduler_API] in the FairScheduler output, it is [missing|https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/webapp/dao/FairSchedulerQueueInfo.java] from the actual output. In case of the CapacityScheduler this field [exists|https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/webapp/dao/CapacitySchedulerQueueInfo.java], but it is missing from the documentation. Let's fix both cases!
