Hi @Tabrez Basha Syed there are a few points regarding the difference between underlying disk block sizes and HDFS block size. The key here is HDFS block size is a logical abstraction on top of the system filesystem rather than a native filesystem of its own. To understand HDFS block size in more detail, I'd recommend reviewing a few good stackoverflow questions: http://stackoverflow.com/questions/13012924/large-block-size-in-hdfs-how-is-the-unused-space-accounted-for http://stackoverflow.com/questions/19473772/data-block-size-in-hdfs-why-64mb For your disk/filesystem recommendations take a look here: https://community.hortonworks.com/content/kbentry/14508/best-practices-linux-file-systems-for-hdfs.html Hope that all helps! ...

Hi @sujitha sanku that's a big question to answer in a short response, but probably the best resource to point you at is the high level sizing calculator which we have on-line here: http://hortonworks.com/blog/how-to-size-your-hadoop-cluster/ There's also a whitepaper linked from there too. Finally, do check out the cluster planning guide documentation for HDP as well: http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.0/bk_cluster-planning-guide/content/ch_hardware-recommendations_chapter.html Hope that helps! ...
