Siddharth Seth updated MAPREDUCE-3943:
--------------------------------------
Attachment: MR3943.txt
Should fix the two issues mentioned previously.
Depends on 3940, and hasn't been tested yet.
stopContainer and getContainerStatus will end up causing exceptions after 2X
rolling interval. Have half a patch to fix that - by remembering older
container specific tokens on the NodeManager - but not very happy with that
approach.
> RM-NM secret-keys should be randomly generated and rolled every so often
