.profile

I had some trouble finding the proper lines to append to my ~/.profile to make it run with Pig until I posted my problem at stackoverflow.com and somebody helped (thank you!):

So now if somebody wants an example for something that is running (but certainly far from perfect):

# if running bash
if [ -n "$BASH_VERSION" ]; then
# include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
. "$HOME/.bashrc"
fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
fi

# set PATH so it includes the system bin if it exists
if [ -d "/bin" ] ; then
PATH="/bin:$PATH"
fi

export HADOOP_HOME=/usr/lib/hadoop
export HADOOP_MAPRED_HOME=/usr/lib/hadoop-mapreduce
export HADOOP_CONF_DIR=/etc/hadoop/conf
export HBASE_HOME=/usr/lib/hbase
export HBASE_CONF_DIR=/etc/hbase/conf
export PIG_HOME=/usr/lib/pig
export PIG_CONF_DIR=/etc/pig/conf

export PATH="$HADOOP_HOME/bin:$HBASE_HOME/bin:$HADOOP_MAPRED_HOME/bin:$PIG_HOME/bin:$PATH"
export PIG_CLASSPATH="`${HBASE_HOME}/bin/hbase classpath`:$PIG_CLASSPATH"

Note that these backticks in the definition of the PIG_CLASSPATH are actually backticks, and not single-quotes!
