Harshit Daga commented on YARN-584:
-----------------------------------
1. Sandy logic is same for both the schedulers , will add a new class as you
suggested to prevent code duplication.
One question can't we put this in some already existing common class ? If you
know let me know else will try to find, if not able to get any class with such
common usage then will go on with adding SchedulerPageUtil class.
With respect to coding pattern will do the changes and update the patch.
2. Steps taken to manually verify patch
1. Tested the patch on my machine with queues and sub queues
example :
a. root -> [root.queue1 and root.queue2]
b. root->[ root.queue1->[root.queue1.queuea , root.queue1.queueb] and
root.queue2]
Test Cases
i. First time page is loading properly : success.
ii. Open (Expand) a queue and reload the page , the queue that was
opened earlier should be open after page is reloaded : success.
iii. Expand (Open) and Unexpand (Close) few queue's and reload the page
again, the queue which were unexpanded before page reload should be unexpanded
even after reload and the one which were in expanded state should be in
expanded state ie. page should look the same even after reload with respect to
queues open/close state. : success.
Tested in chrome (version 30.0.1599.101), Safari(Version 6.1 (7537.71))
and Firefox(version 20.0)
System : Mac OS X (version 10.7.5)
3. For "The patch appears to cause the build to fail."
I added my patch to checked out trunk using patch -p0 <
YARN-584-branch-2.2.0.patch ( at root folder )
and then build it using mvn install -DskipTests and I got a BUILD SUCCESS
can you why log is showing build fail ?

> Labels: newbie
> Attachments: YARN-584-branch-2.2.0.patch

> In the fair scheduler web UI, you can expand queue information. Refreshing
> the page causes the expansions to go away, which is annoying for someone who
> wants to monitor the scheduler page and needs to reopen all the queues they
> care about each time.
