Hi
Can any one you let me know what command do I need to execute for
Decommissioning TaskTracker?
Datanode decommissioning I have achieved using hadoop dfsadmin
-refreshNodes.
Similar to HDFS is there any command for Mapreduce Decommission.
I have gone through the defect [HADOOP-5643 ] ..but I was unable to find
what command I need to execute.
I have tried ./mapred jobtracker -decommission but not working .
There is no command in HDFS like this .
U must specify the hosts to exclude in mapred.hosts.exclude parameter in
mapred.site.xml
And
hadoop dfsadmin -refreshNodes.
is sufficient to do the work.
Please help me .
Thanks
sandeep
