Attachment: SchedulerActivityManager-TestReport.pdf
HI [~ChenGe] and [~leftnoteasy]
I got some time to do test with this patch. I thought of sharing test results
here along with few inputs.
I added this comments in the doc as well.
Comments:
# I think Diagnostic message could be improved. "do not need more resource" =>
“Applications does not need more resource”
# For node activity, "priority": "-1" does not make sense. Could we hide the
same from node level and show for app (container)?
# timeStamp is not meaningful ("timeStamp": "1469792611186"). Its could be date
and time or relative to previous activity.
# *finalAllocationState* is one of the entry for application. Could we say
*finalAppAllocationState*.
# In queue level, is “allocationState” meaningful? I think we can hide in queue
level, thoughts.?
# As mentioned earlier, priority could be hidden in places where its -1.
# As an improvement, its better to give pending resource requests per app after
allocation. So we can get some idea and can help a lot.
# when I tested below test case "allocation for an application is done and app
is running. Second app is awaiting due to AM resource percentage." I could not
get expected result. Am I missing something.? Test case 6 in the report.
# Could we also print node_label too when container is allocated
I tried some more cases and will try enhancing this report.
