Zhankun Tang commented on YARN-10048:
-------------------------------------
[~Sen Zhao], thanks for catching this. Let me understand this, there's a
mismatch between the founded controller path and the configured value when
there's multiple path under cpu subsystem?
And could you please also show the error message when NM fails to crash? Thanks!
