farmmamba commented on HDFS-17199:
----------------------------------
I found two replicas methods in class ReplicaMap. One is thread-safe and
another is not.
The one which is not thread-safe is used in readReplicasFromCache. Although
there is not race condition problem here, I think we'dÂ
better drop the non-thread-safe replicas method and only keep the thread-safe
one left.
> LightWeightResizableGSet#values() seems not thread-safe.
