>                 Key: HDFS-16909
>                 URL: https://issues.apache.org/jira/browse/HDFS-16909
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: datanode
>    Affects Versions: 3.3.4
>            Reporter: ZhangHB
>            Priority: Minor
>              Labels: pull-request-available
>
> Currently, the code is as below:
> {code:java}
> for (ReplicaInfo replicaInfo : replicaSet) {
>   checkBlock(replicaInfo);
>   if (curSet == null) {
>     // Add an entry for block pool if it does not exist already
>     curSet = new LightWeightResizableGSet<>();
>     map.put(bp, curSet);
>   }
>   curSet.put(replicaInfo);
> } {code}
> the statment :
> {code:java}
> if(curSet == null){code}
> should be moved to outside from the for loop.
