Hi Shane, list, I have no knowledge of HDFS at all. Why would someone choose CephFS instead of HDFS for Hadoop ? HDFS is meant for Hadoop right ? I may have to work on Hadoop in a few months, so I'd like to be able to do the right choice.
One common motivation for using something other than HDFS is that a site has an existing filesystem for other applications, and wants to plug Hadoop into that instead of creating a separate HDFS silo. Different distributed FS options (HDFS, cephfs, lustre etc) all have different price/performance tradeoffs too, and some folks have more I/O intensive workloads than others -- it's just like how you shop for storage with any other application.
