    Question Hadoop multinode cluster installation

    Hello everyone.
    I have facing a problem on installation of hadoop multinode cluster. I have installed single node cluster in 2 machines and configured the conf folder of both machines. i have taken one as master machine and another as slave. When i execute start-all.sh on master machine all the parameters are enabled properly on master but didnt enable on slave. When i execute start-all.sh on master iam getting eror that cannot copy log files into slave.

    The error is as below,

    hadoop@user-G41M-Combo:/usr/local/hadoop/hadoop$ bin/start-all.sh
    namenode running as process 25724. Stop it first.
    slave: mv: cannot move `/usr/local/hadoop/hadoop/bin/../logs/hadoop-hadoop-datanode-user-HP-dx2480-MT-NA125PA.out' to `/usr/local/hadoop/hadoop/bin/../logs/hadoop-hadoop-datanode-user-HP-dx2480-MT-NA125PA.out.1': Permission denied

    These support forums are for Zimbra Collaboration Server, what does your question have to do with that? Have you tried the support forums for the product you're trying to install?
