> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 3.1.1
> Reporter: Yiqun Lin
> Assignee: Surendra Singh Lilhore
> Priority: Major
>
> This is a follow-up work for HDFS-13768. Mainly two places needed to update:
> * Add null check for add-replica pool to avoid lock acquiring
> * In {{ReplicaMap#addAndGet}}, it would be better to use
> {{FoldedTreeSet#addOrReplace}} instead of {{FoldedTreeSet#add}} for adding
> replica info.
