title: Issues with installing Hive on Ubuntu: $HADOOP_HOME or $HADOOP_PREFIX must be set or hadoop must be in the
body: <p>I have installed Hadoop on my Ubuntu EC2 instance and have gone through all the steps for installing hive following this tutorial: <a href="http://www.tutorialspoint.com/hive/hive_installation.htm" rel="nofollow">http://www.tutorialspoint.com/hive/hive_installation.htm</a></p>
  
  <p>However, when I go to launch hive I get the following error message:</p>
  
  <p>"Cannot find hadoop installation: $HADOOP_HOME or $HADOOP_PREFIX must be set or hadoop must be in the path"</p>
  
  <p>My bashrc file reads this:</p>
  
  <pre><code>export JAVA_HOME=/usr
  export PATH=$PATH:$JAVA_HOME/bin
  export HADOOP_HOME=/usr/local/hadoop-2.7.1
  export PATH=$PATH:$HADOOP_HOME/bin/
  
  
  export HADOOP_MAPRED_HOME=$HADOOP_HOME
  export HADOOP_COMMON_HOME=$HADOOP_HOME
  export HADOOP_HDFS_HOME=$HADOOP_HOME
  export YARN_HOME=$HADOOP_HOME
  export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
  export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin
  
  
  export HIVE_HOME=/usr/local/hive
  export PATH=$PATH:$HIVE_HOME/bin
  export CLASSPATH=$CLASSPATH:/usr/local/hadoop-2.7.1/lib/*:.
  export CLASSPATH=$CLASSPATH:/usr/local/hive/lib/*:.
  
  export DERBY_HOME=/usr/local/derby
  export PATH=$PATH:$DERBY_HOME/bin
  </code></pre>
  
  <p>Does anyone have any suggestions on how to fix this? I presume it's an issue with how I have linked my Hadoop and hive,</p>
  
  <p>Thanks in advance,</p>
