[jira] [Commented] (YARN-5402) Fix NoSuchMethodError in ClusterMetricsInfo

["Weiwei Yang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-5402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15383509#comment-15383509 ] 

Weiwei Yang commented on YARN-5402:
-----------------------------------

Jersey uses reflection to call QueueMetrics methods, {{QueueMetrics.getReservedMB}} returns {{int}} but it is looking for {{long}}

* getAvailableMB
* getAllocatedMB
* getReservedVirtualCores
* getAvailableVirtualCores
* getAllocatedVirtualCores

they all have same issues. And {{UserMetricsInfo}} also has this problem. Uploaded a patch to fix this.
