    Is there any advantage to configure the data nodes with RAID-5 vs 4 separate partitions?

    Hi Li,

    RAID has its own advantages when used in right context. But when considered for Hadoop (especially the data nodes), you would not be benefitted. The data redundancy is inbuilt in the HDFS. HDFS and MapReduce helps you have redundant copies of data as well as get better data locality while data processing.
    So JBODs will give you better benefits over RAID for data nodes.
