What does this error when I'm trying to run an example in Apache Mahout?
config, hadoop, mahout
Solution
This is nothing to do with Mahout or Hadoop, but your shell. You appear to be using `HADOOP_HOME` instead of `$HADOOP_HOME` in your path expression somewhere, for example.
Problem
I configured and ran examples with mahout but I get the following error : hadoop binary is not in PATH,HADOOP_HOME/bin,HADOOP_PREFIX/bin, running locally Error occurred during initialization of VM In my, `.bashrc`, I defined the following aliases : JAVA_HOME,HADOOP_CONF_DIR,MAHOUT_CONF_DIR,HADOOP_HOME I already have configured this in `/etc/bash.bashrc` : - `export JAVA_HOME=/usr/lib/jvm/java-6-openjdk-i386` - `export PATH=$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.`
