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>*
