Lin Yiqun commented on HDFS-10359: ---------------------------------- Hi, [~Tao Jie], I don't think this is a good idea. If I trigger all the datanode in my cluster, it will flood my namenode with block report. Maybe the property of {{dfs.blockreport.initialDelay}} can be used for that, but I still think remain the original command unchanged will be better. > Allow trigger block report from all datanodes > --------------------------------------------- > > Key: HDFS-10359 > URL: https://issues.apache.org/jira/browse/HDFS-10359 > Project: Hadoop HDFS > Issue Type: Improvement > Components: datanode > Affects Versions: 2.7.0, 2.6.1 > Reporter: Tao Jie > > Since we have HDFS-7278 allows trigger block report from one certain > datanode. It would be helpful to add a option to this command to trigger > block report from all datanodes. > Command maybe like this: > *hdfs dfsadmin -triggerBlockReport \[-incremental\] > <datanode_host:ipc_port|all>* -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
