S3 bucket for HDFS

  • #51963
    Prabhat Singh


    I need to add s3 bucket for hdfs.
    While launching clusters, I add following property(key, value) in hdfs-site.xml through browser

    But the installation fails afterwards(at Datanode). Please advice.

    Hi Prahbat,

    Could you please share the error message from the datanode.log?

    I did a few more changes.
    I am adding my bucket as s3://hbkt in fs.defaultFS of “main/services/HDFS/configs>Advanced”.
    Then added the key and secret id in custom core-site.xml area of the page.

    here is the log of error.
