We added the new machines and configured it to all Disk. Working fine so far.

Hey together, we're running a CDP Private Cloud Base Cluster with actually 6 Nodes. All 6 Nodes running fully on SSD storage. I found out that HDFS thinks the SSDs are normal disk, because it is not configured as SSD storage like this --> "[SSD]/grid/n/dn", actually its "/grid/n/dn". Now we're planning to add four other servers from an older cluster with normal disks. My action plan is as follows: 1. configure existing storage/server to SSD -> "[SSD]/grid/n/dn" 2. add the other four server an configure it -> "[DISK]/grid/n/dn" 3. restart recommended services I've got the following questions: - Will HDFS distribute the blocks across all nodes (SSD and disk?) without any storage policy configured? So that we have a homogeneous storage. - How will services react to this changes in storage, for example HBase? - If we configure a homogeneous storage, as i described: does reconfiguring the storage paths of the Datanodes to SSDs add any value/benefit at all? Thanks for your help! Regards, Timo
