zhtttylz opened a new pull request, #6504:
URL: https://github.com/apache/hadoop/pull/6504
JIRA: HDFS-17146. Use the dfsadmin -reconfig command to initiate
reconfiguration on all decommissioning datanodes.
If the DFSAdmin command could have the ability to perform bulk operations
across all decommissioned datanodes, that would be highly advantageous.
### How was this patch tested?
Dev cluster and UT.
When the cluster node status is as follows:
```
Hostname: hadoop-node1
Decommission Status : Decommission in progress
Hostname: hadoop-node2
Decommission Status : Decommission in progress
Hostname: hadoop-node3
Decommission Status : Normal
[hadoop@hadoop-ops bin]$ hdfs dfsadmin -reconfig datanode decomnodes start
Started reconfiguration task on node [hadoop-node1:9867].
Started reconfiguration task on node [hadoop-node2:9867].
Starting of reconfiguration task successful on 2 nodes, failed on 0 nodes.
