Rohith Sharma K S commented on YARN-4837:
-----------------------------------------
Thanks [~vinodkv] for working on the patch!!. Overall approach reasonable to
me, and going through patch more on depth.
One suggestion is can default value for threshold reduce to less than 50%? May
be reasonable value is 20% or 10% so that probability of occurring issues like
YARN-4685 can be reduced.
{code}
public static final float
DEFAULT_AM_SCHEDULING_NODE_BLACKLISTING_DISABLE_THRESHOLD =
0.8f;
