Hi Sean,

Thanks for the inputs.

What is the normal/ideal location to set a mount point ?

Yes, I plan to use Ambari for the configs. once the disks are ready to be used for the datanodes.

Omkar - Yes, with HDFS (nothing HDP specific) you mount each drive separately.

Where you mount them doesn’t matter, but never set a mount point under /dev.

This talks to the various configuration settings to update to match those dirs, but you would
do them from Ambari instead of editing the configuration files manually:

I have 600GB X 8 disks on each machine that can be used for HDP.

1 disk is used for the /root, /home etc. so I'm now left with 7 disks.

If I understand correctly from the HDP recos
, I can MOUNT these 7 disks as:


Where each disk will have a ONE SINGLE BIG partition with ext3/ext4.
