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

             Summary: Specification of HADOOP_CONF_DIR via the environment in hadoop_config.cmd
                 Key: HADOOP-10140
                 URL: https://issues.apache.org/jira/browse/HADOOP-10140
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 2.2.0
         Environment: This Windows when using the "Command" processing as opposed to using Bash from Cygwin.
            Reporter: Ian Jackson
            Priority: Minor


It would be nice if HADOOP_CONF_DIR could be set in the environment like YARN_CONF_DIR. This could be done in lib-exec/hadoop.cmd by setting HADOOP_CONF_DIR conditionally.

Using the Windows command shell, the modification would be as follows:
if not defined HADOOP_CONF_DIR (
set HADOOP_CONF_DIR=%HADOOP_HOME%\etc\hadoop
)

This would allow the Hadoop configuration to be placed in ProgramData more easily.
