Subject [jira] [Commented] (MAPREDUCE-7069) Add ability to specify user environment variables individually
Date Tue, 10 Apr 2018 22:00:00 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-7069?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16433057#comment-16433057

Shane Kumpf commented on MAPREDUCE-7069:
----------------------------------------

Thanks for the patch [~Jim_Brennan]! I'm working on testing this out.

One minor, optional, nit in the meantime. Considering convention for environment variables,
it might be clearer to make the variable names uppercase in the various docs (VARNAME instead
of varName, VAR1 instead of var1, etc).

> As reported in YARN-6830, it is currently not possible to specify an environment variable
that contains commas via {{mapreduce.map.env}}, mapreduce.reduce.env, or {{mapreduce.admin.user.env}}.
> To address this, [~aw] proposed in [YARN-6830] that we add the ability to specify environment
variables individually:
> {quote}e.g, mapreduce.map.env.[foo]=bar gets turned into foo=bar
> {quote}
