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'd better drop the non-thread-safe replicas method and only keep the thread-safe one left. > LightWeightResizableGSet#values() seems not thread-safe. > -------------------------------------------------------- > > Key: HDFS-17199 > URL: https://issues.apache.org/jira/browse/HDFS-17199 > Project: Hadoop HDFS > Issue Type: Improvement > Components: datanode > Affects Versions: 3.4.0 > Reporter: farmmamba > Assignee: farmmamba > Priority: Major > -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
