Description

Hadoop (and many of the other projects in the hadoop stack) have a HADOOP_CONF_DIR (<project>_CONF_DIR) environment variable that is used to start daemons using the configuration specified.

This is convenient because it decouples the configuration from the distributions – daemons can be run with different configs without having to perform stateful file operations.

For example one could run accumulo like this:

ACCUMULO_CONF_DIR=/etc/accumulo/conf accumulo ....

or set env variables in .bashrc/jenkins scripts for different configurations

export ACCUMULO_CONF_DIR=$ACCUMULO_HOME/conf/examples/1GB/standalone
.. run test

export ACCUMULO_CONF_DIR=$ACCUMULO_HOME/conf/examples/1GB/native-standalone
.. run test
