[jira] [Comment Edited] (YARN-9578) Add limit/actions/summarize
options for app activities REST API
[ https://issues.apache.org/jira/browse/YARN-9578?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16854553#comment-16854553 ]

---------------------------------------------------------
For better serving to users, we should support more options for app activities REST API:
# limit - set a limit of the result, user often need only 1 or a few latest activities, this option can lower the cost from both server and client sides in some scenarios.
# actions - the required actions of app activities including UPDATE and GET, some scenarios such as app attempt UI would like to refresh and show the latest activities, perhaps will trigger updating at first then get latest activities after a while, customized actions can drop unnecessary actions to cut the cost.
# summarize - whether app activities in multiple scheduling processes need to be summarized, it's useful when multi-node disabled since only one node can be considered in a single scheduling process, enable this may give us a summary with diagnostics on all nodes for better debugging.
