priority labels
[ https://issues.apache.org/jira/browse/YARN-2693?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sunil G updated YARN-2693:
--------------------------
Attachment: 0001-YARN-2693.patch
Uploading a work in progress patch for priority label manager.
* Supporting file system and memory store
* Handling 4 events to store such as add_labels_to_queue, remove_labels_from_queue, store_cluster_labels, remove_cluster_labels
* Using specific pb impls to store the labels details to file
* Design similar to node label manager, however changes in event specific handling is done
* RMPriorityLabelManager class has to be on top of this as a wrapper, which we can bring up as RM core changes
Kindly review and provide major comments. I will keep updating this with tests also.
