---------------------------------------------------------------
Patch 1 includes support for cancel upgrade.
To test the patch :
1. yarn app -launch test1 sleeper
2. yarn app -upgrade test1 -initiate sleeper_v2.json
3. yarn app -upgrade test1 -instances sleeper-0
4. yarn app -upgrade test1 -cancel
[~eyang] [~gsaha] Could you please review?
Please note that with my changes, the ServiceAM will only send a second reinit
request for the same container until it has received a response from the NM for
previous reinit request.
I see an intermittent issue with NM when there are subsequent reinitialization
requests made for the same container. NM sends premature response back to
ServiceAM that container is running but the state of the container in NM is
still {{REINITIALIZING_AWAITING_KILL}}. This is hard to reproduce manually.
Since this is a NM side bug, I am going to open a new ticket to fix it.
