Botong Huang commented on YARN-7953:
------------------------------------
bq. line 160, super.clone() is redundant.
Then either use the object from _rationGlobalView) super.clone()_ with
necessary modification (deep copy), or remove cloneable interface and change
signature to _static clone()_ then. Basically avoid creating new two copied
objects and using only one.
bq. line 47, this is a tree of queues rather than a single queue right?
Agreed. What I meant is the javadoc description:
This class represent a queue at the federation level -> This class represent a
tree of queues in a sub-cluster YarnRM.
