  Hi!

  Thank you so much for the video.
  I was having the same problem as you and those extra « exports » for the 64 bit version seemed to solve them, at least so far 🙂

  How were you able to figure this out?

  Regards,
  Amin

    Hi,

    I found it somewhere on the net after some research. That really should be part of their manual.

    Cheers

    Hi,
    I have installed Hadoop as per your guidlines. But when i run bin/hadoop, its showing hadoop: command not found.

    Please suggest me how to rectify this issue & also I am a new for Linux OS and first time i have installed Linux OS & trying to install Hadoop.

    My System info:
    LinuxMint 17 LTS 32 bit

    Steps followed for Hadoop Installation:
    Step1: sudo -i
    Step2: apt-get update
    Step3: apt-get -y install python-software-properties (I already have Java Software. installed in the path of « /opt/java/jdk1.8.0_11 »
    Step4: adduser hadoop
    Step5: cd /usr/local
    Step6: wget http://apache.mirror.iweb.ca/hadoop/common/hadoop-2.4.0/hadoop-2.4.0.tar.gz
    Step7: tar -zxf hadoop-2.4.0.tar.gz
    Step8: ln -s hadoop-2.4.0 hadoop
    Step9: chown -R hadoop:hadoop hadoop-2.4.0 hadoop
    Step10: sudo -i -H -u hadoop
    Step11: cd /usr/local/hadoop
    Step12: gedit etc/hadoop/hadoop-env.sh

    Error:
    No protocol specified

    (gedit:4788): Gtk-WARNING **: cannot open display: :0

    Step13: Manually opened hadoop-env.sh file add the below two lines

    export JAVA_HOME=/opt/java/jdk1.8.0_11
    export HADOOP_PREFIX=/usr/local/hadoop

    Step14: bin/hadoop
    Showing the folloiwng info in Terminal
    Usage: hadoop [–config confdir] COMMAND
    where COMMAND is one of:
    fs run a generic filesystem user client
    version print the version
    jar run a jar file
    checknative [-a|-h] check native hadoop and compression libraries availability
    distcp copy file or directories recursively
    archive -archiveName NAME -p * create a hadoop archive
    classpath prints the class path needed to get the
    Hadoop jar and the required libraries
    daemonlog get/set the log level for each daemon
    or
    CLASSNAME run the class named CLASSNAME

    Most commands print help when invoked w/o parameters.

    Step15: Could not run remaining steps from here

    Thanks & Regards,
    Bhaskar

      Hi Bhaskar,

      When you want to run hadoop, make sure you are in the right directory (i.e. cd /usr/local/hadoop )

      For step12, you cannot use gedit if you are not in a visual environment. That`s why I use vim.

      Cheers

  I have followed every step here to install Hadoop-2.5.0-src on Ubuntu 64-bit system. With a difference that I could locate hadoop-env.sh file in « /usr/local/hadoop/hadoop-common-project/hadoop-common/src/main/conf ». Then edited that following the vim command as tutored but then bin/hadoop returns « no such file or directory ». What should be done? [Beginner]

    Hi, the problem is that you took the « src » version. Which means that you have the source code and you would need to compile it before using it.
    Take this one: http://mirror.its.dal.ca/apache/hadoop/common/hadoop-2.5.0/hadoop-2.5.0.tar.gz

    Hi Andrew,

    this is hard to tell since I haven’t tried this tutorial with 2.5.0, but 2.4.0 and I don’t know all the steps you did.

  Hi,

  This is a nice video and as I followed everything was going fine until I executed the command:

  bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.4.0.jar grep input output ‘dfs[a-z.]+’

  It was showing error:

  java.net.ConnectException: Call From arindam/127.0.1.1 to localhost:9000 failed on connection exception: java.net.ConnectException: Connection refused

  My working environment is Ubuntu 14.04.

  Handy video (likely to point a number of people to it).

  One small thing. ‘ll’ while a pretty command alias for people to use, it not standard by any means.

  I would suspect a lot of people watching would get a bit confused by it despite it having nothing to do with hadoop.
