Hello Steven ,
You can use dfs.datanode.du.reserved configuration value in
$HADOOP_HOME/conf/hdfs-site.xml for limiting disk usage.
<property>
<name>dfs.datanode.du.reserved</name>
<!-- cluster variant -->
<value>182400</value>
<description>Reserved space in bytes per volume. Always leave this much
space free for non dfs use.

</property>

hi, guys,
we have some machine with 1T disk, some with 100GB disk,
I have this question that is there any means we can limit the
disk usage of datanodes on those machines with smaller disk?
thanks!
Ravi
