    Am pulling the data with help of flume(log files)

    How can i copy those files from outside to HDFS?

    Hi Tnr,
    This can potentially mean datanodes are not accessible where you are running the flume client. Can you try doing hadoop fs -put command from the client machine that is running flume to send files to HDFS?
