----------------------------------------

             Summary: Create ACCUMULO_CONF_DIR environment variable
                 Key: ACCUMULO-1550
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1550
             Project: Accumulo
          Issue Type: Bug
          Components: scripts
    Affects Versions: 1.5.0, 1.4.3, 1.6.0
            Reporter: Jonathan Hsieh
            Assignee: Jonathan Hsieh


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:

{code}
ACCUMULO_CONF_DIR=/etc/accumulo/conf accumulo ....
{code}

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

{code}
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
{code}
