[jira] [Updated] (YARN-3143) RM Apps REST API can return NPE or
entries missing id and other fields
[ https://issues.apache.org/jira/browse/YARN-3143?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kendall Thrapp updated YARN-3143:
---------------------------------
Description:
I'm seeing intermittent null pointer exceptions being returned by
the YARN Apps REST API.
For example:
{code}
http://{cluster}:{port}/ws/v1/cluster/apps?finalStatus=UNDEFINED
{code}
JSON Response was:
{code}
{"RemoteException":{"exception":"NullPointerException","javaClassName":"java.lang.NullPointerException"}}
{code}
At a glance appears to be only when we query for unfinished apps (i.e. finalStatus=UNDEFINED).
Possibly related, when I do get back a list of apps, sometimes one or more of the apps will be missing most of the fields, like id, name, user, etc., and the fields that are present all have zero for the value.
For example:
{code}
{"progress":0.0,"clusterId":0,"applicationTags":"","startedTime":0,"finishedTime":0,"elapsedTime":0,"allocatedMB":0,"allocatedVCores":0,"runningContainers":0,"preemptedResourceMB":0,"preemptedResourceVCores":0,"numNonAMContainerPreempted":0,"numAMContainerPreempted":0}
{code}
Let me know if there's any other information I can provide to help debug.
