Rita M commented on HDFS-1564:
------------------------------
Harsh,
Definitely as Byte opt, one value per disk.
Here is how I would do the use case,
Define the partition
<property>
<name>dfs.data.dir.0</name>
<value>/fs1</value>
<final>true</final>
</property>
<!-- reserve 1% on /fs1 -->
<property>
<name>dfs.data.dir.0.reservepct</name>
<value>1</value>
<final>true</final>
</property>
Any thoughts about this?
