Subject [jira] Commented: (HADOOP-555) Tasks should inherit some of the server's environment
Date Mon, 25 Sep 2006 22:42:51 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-555?page=comments#action_12437685 ] 
Doug Cutting commented on HADOOP-555:

I'm confused.  Don't child processes inherit their parent's environment?  They should.

You should be able to set LD_LIBRARY_PATH, PATH, etc. in conf/hadoo-env.sh and these should
be seen by the child.  If that doesn't work, I think it's a bug that should be fixed.  If
it does work, is it sufficient?

> When the task trackers start up the Task process, they clear the environment variables.
It would be better if there was a SERVER config that listed the names of the environment variables
that would be copied from the server's enviroment.
> So the task tracker's config would have:
> <property><name>mapred.task.environment</name>
> <value>PATH,LD_LIBRARY_PATH</value></property>
