Hi,
Hadoop-1's name node UI displays dead datanodes
even if those instances are terminated and are not part of the cluster
anymore.
Is there a way to reset the dead datenode list without bouncing namenode ?
This would help me in my script(which would run nightly) which parses the
html page,termina
I believe there's some command to show list of datanodes from CLI, using
parsing HTML is not a good idea. HTML page is intended to be read by human.
I also don't know how to refresh node list;
Regards,

You can add the hostname/IP in exclude file and run this command
hadoop dfsadmin -refreshNodes.

If by resetting the list of dead datanodes you mean the web-console or the
report command not showing the datanode that you removed, in this case you
will have to do the following:
1. Remove the entry from the slaves file corresponding to the dead datanode.
2. Remove entry from exclude file
3. Run
