      Description

      The JAVA_HOME directory remains unchanged no matter what you enter when you run hadoop-setup-conf.sh to generate hadoop configurations. Please see below example:

      *********************************************************
      [root@hadoop-slave ~]# /sbin/hadoop-setup-conf.sh
      Setup Hadoop Configuration

      Where would you like to put config directory? (/etc/hadoop)
      Where would you like to put log directory? (/var/log/hadoop)
      Where would you like to put pid directory? (/var/run/hadoop)
      What is the host of the namenode? (hadoop-slave)
      Where would you like to put namenode data directory? (/var/lib/hadoop/hdfs/namenode)
      Where would you like to put datanode data directory? (/var/lib/hadoop/hdfs/datanode)
      What is the host of the jobtracker? (hadoop-slave)
      Where would you like to put jobtracker/tasktracker data directory? (/var/lib/hadoop/mapred)
      Where is JAVA_HOME directory? (/usr/java/default) /usr/lib/jvm/jre
      Would you like to create directories/copy conf files to localhost? (Y/n)

      Review your choices:

      Config directory : /etc/hadoop
      Log directory : /var/log/hadoop
      PID directory : /var/run/hadoop
      Namenode host : hadoop-slave
      Namenode directory : /var/lib/hadoop/hdfs/namenode
      Datanode directory : /var/lib/hadoop/hdfs/datanode
      Jobtracker host : hadoop-slave
      Mapreduce directory : /var/lib/hadoop/mapred
      Task scheduler : org.apache.hadoop.mapred.JobQueueTaskScheduler
      JAVA_HOME directory : /usr/java/default
      Create dirs/copy conf files : y

      Proceed with generate configuration? (y/N) n
      User aborted setup, exiting...
      *********************************************************

      Resolution:
      Amend line 509 in file /sbin/hadoop-setup-conf.sh

      from:

      JAVA_HOME=$

      {USER_USER_JAVA_HOME:-$JAVA_HOME}

      to:

      JAVA_HOME=$

      {USER_JAVA_HOME:-$JAVA_HOME}

      will resolve this issue.
