Subject [jira] [Resolved] (HADOOP-10140) Specification of HADOOP_CONF_DIR via the environment in hadoop_config.cmd
Date Thu, 12 Feb 2015 00:42:13 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-10140?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Chris Nauroth resolved HADOOP-10140.
       Resolution: Fixed
    Fix Version/s: 2.7.0
     Hadoop Flags: Reviewed

+1 for the patch.  I committed this to trunk and branch-2.

I did a test run of starting the daemons and running a few commands through all 4 main script
entry points: hadoop, hdfs, mapred and yarn.  Everything worked as expected.

Kiran, thank you for contributing the fix.

Bash from Cygwin.

> 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.
