# Set Hadoop-specific environment variables here.

# The only required environment variable is JAVA_HOME.  All others are

# remote nodes.

# The java implementation to use.  Required.
# export JAVA_HOME=/usr/bin/java

# The maximum amount of heap to use, in MB. Default is 1000.

# Extra ssh options.  Default: '-o ConnectTimeout=1 -o SendEnv=HADOOP_CONF_DIR'.
# export HADOOP_SSH_OPTS="-o ConnectTimeout=1 -o SendEnv=HADOOP_CONF_DIR"

# Where log files are stored.  $HADOOP_HOME/logs by default.
# export HADOOP_LOG_DIR=${HADOOP_HOME}/logs

# File naming remote slave hosts.  $HADOOP_HOME/conf/slaves by default.
# export HADOOP_SLAVES=${HADOOP_HOME}/conf/slaves

# host:path where hadoop code should be rsync'd from.  Unset by default.
# export HADOOP_MASTER=master:/home/$USER/src/hadoop

# The directory where pid files are stored. /tmp by default.
