Lin Yiqun created HDFS-9685: ------------------------------- Summary: StopDecommission for datanode should remove the underReplicatedBlocks Key: HDFS-9685 URL: https://issues.apache.org/jira/browse/HDFS-9685 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 2.7.1 Reporter: Lin Yiqun Assignee: Lin Yiqun
When one node removed from exclude file, and its state from decommission-in-progress to in service. But the underReplicatedBlocksNum of cluster has not been decreased. Most of these underReplicatedBlocks are not needed and it will costs namenode much time to deal with. And frequently namenode will find there are enough replications. So in {{stopDecommissioned}} operation, we should remove neededReplicatedBlocks of decomNodes. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
