Steve Loughran commented on YARN-1179:
--------------------------------------
The actual value needed is {{containerWorkDir}} built in {{ContainerLaunch}};
the selection of this directory could be pulled up and used in variable
expansion.
> add ApplicationConstants option to define base dir of the installed
> application
> -------------------------------------------------------------------------------

> Key: YARN-1179
> URL: https://issues.apache.org/jira/browse/YARN-1179
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: nodemanager
> Affects Versions: 2.1.0-beta
> Reporter: Steve Loughran
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> There is no expanded env variable for the directory into which the NM copies
> down local resources and executes the supplied command(s). This prevents you
> creating environment variables in the context that set absolute paths
> {code}
> env.put("CONF_DIR",absolute path to "/conf")
> {code}
> This could be determined by resolving "." to an absolute value in bash
> scripts, but it would be easier and safer if we just had an auto-expanding
> env variable
> {code}
> env.put("CONF_DIR","<INSTALL_DIR>/conf")
> {code}
> And of course {{INSTALL_DIR}} would be declared in {{ApplicationConstants}}.
