Hi all,
We would like to decommission nodes to run jobs with less number of map and
reduce and then scale it up. In this process we want to decommission the nodes
and then bring back.
Does decommissioning work? We have defined dfs.hosts.exclude with a path to the
file that has list of nodes to exclude: in core-site.xml Also did a "refresh"
after making these changes.
<property>
<name>dfs.hosts.exclude</name>
<value>/home/testuser/decommission_nodes.txt</value>
<description>Excluding the nodes in the file</description>
</property>

Please advice
Thank you,
Amit
