Tsuyoshi OZAWA commented on YARN-1474:
--------------------------------------
Thanks Karthik for the comments. I'd like to make sure one point:
{quote}
1. In each of the schedulers, I don't think we need the following snippet or
for that matter the variable initialized at all. reinitialize() would have just
the contents of else-block.
{quote}
If we change that {{reinitialize()}} would have just contents of else-black, we
need to change lots schedulers-related test cases without
ResourceManager/MockRM to call {{scheduler.init()}} right after
{{scheduler.setRMContext()}}. Is it acceptable for us?
