Question

I configured and ran examples with mahout but I get the following error :

hadoop binary is not in PATH,HADOOP_HOME/bin,HADOOP_PREFIX/bin,
running locally Error occurred during initialization of VM

In my, .bashrc, I defined the following aliases :

JAVA_HOME,HADOOP_CONF_DIR,MAHOUT_CONF_DIR,HADOOP_HOME

I already have configured this in /etc/bash.bashrc :

• export JAVA_HOME=/usr/lib/jvm/java-6-openjdk-i386
• export PATH=$PATH:$JAVA_HOME/bin
• export HADOOP_HOME=/home/user/hadoop-0.20.2
• export PATH=$PATH:$HADOOP_HOME/bin
• export MAHOUT_HOME=/home/user/mahout/trunk
• export classpath=$classpath:$MAHOUT_HOME/src/conf
• export HADOOP_CONF_DIR=/home/user/hadoop-0.20.2/conf
• export classpath=$classpath:$HADOOP_CONF_DIR

However, I have the following error :

MAHOUT_LOCAL is set, so we don't add HADOOP_CONF_DIR to classpath. Error: Could not find or load main class classpath MAHOUT_LOCAL is set, running locally Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine.

Answer 1

This is nothing to do with Mahout or Hadoop, but your shell. You appear to be using HADOOP_HOME instead of $HADOOP_HOME in your path expression somewhere, for example.
