Hi list,I added a property dfs.hosts.exclude to my conf/hadoop-site.xml. Then refreshed my cluster with command bin/hadoop dfsadmin -refreshNodes It showed that it can only shut down the DataNode process but not included the TaskTracker process on each slaver specified in the excludes file.
Presently, decommissioning TaskTracker on-the-fly is not available.
The jobtracker web still show that I hadnot shut down these nodes. How can i totally decommission these slaver nodes on-the-fly? Is it can be achieved only by operation on the master node?
I think one way to shutdown a TaskTracker is to kill it. Thanks Amareshwari
Thanks, Jeremy
