Hello Tadas,

       It is actually a good option to have multiple disks attached to a machine often referred
to as JBOD (just a bunch of disks) configuration. Just have to add the properties as specified
my Mr. Nitin.

you can have multiple partitions (multiple directories)

when you setup your hdfs you will need to set

<property>
<name>dfs.data.dir</name>
<value>dir1,
dir2
<final>true</final>
</property

I have several physical machines with two mounted hard disks each. Now going through partitioning
process and not sure  should I leave partitions according to the disk size or it’s better
to merge them as one?

As I will have just one JT, DN per server not sure how multiple partitions will be handled
within Hadoop. Do they perform in such a manner?

Thanks, Tadas
