    When I try to connect to Hadoop in my compartment from my Autonomy server to test Hadoop connector I get the error listed below, the settings from Autonomy connector job is:

    FileSystemRootUri=hdfs:// [IP address]:50070/webhdfs/v1
    FileSystemPath=/tmp/

    Here is the log:

    Hi Ardavan,

    Not being familiar with Autonomy I can only guess, but have you tried to use the fully qualified host name rather than the ip? Hadoop in general prefers that you use hostnames rather than ips. And just to make sure here when you installed Hadoop did you use the Fully Qualified Host Names or the IP addresses?

    Thanks,
    Ted.
