Viraj Jasani created HDFS-16163: ----------------------------------- Summary: Avoid locking entire blockPinningFailures map Key: HDFS-16163 URL: https://issues.apache.org/jira/browse/HDFS-16163 Project: Hadoop HDFS Issue Type: Improvement Reporter: Viraj Jasani Assignee: Viraj Jasani
In order for mover to exclude pinned blocks in subsequent iteration, we try to put pinned blocks in a map of blockIds to set of Datanode sources. However, while updating an entry of this map, we don't need to lock the entire map. We can use fine-grained concurrency here. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
