Chris Nauroth commented on MAPREDUCE-4959:
------------------------------------------
HADOOP-8899 added the classpath jar bundling logic to branch-1-win. YARN-316
is porting that logic to YARN on branch-trunk-win. While working on the YARN
port, I discovered these issues with handling of environment variables and
wildcards. The YARN-316 patch will handle these cases for YARN. I'm filing
this jira to backport the same logic to branch-1-win.
> bundling classpath into jar manifest on Windows does not expand environment
> variables or wildcards

> Key: MAPREDUCE-4959
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4959
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: tasktracker
> Affects Versions: 1-win
> Reporter: Chris Nauroth
>
> To support long classpaths on Windows, the class path entries get bundled
> into a small temporary jar with a manifest that has a Class-Path attribute.
> When a classpath is specified in a jar manifest like this, it does not expand
> environment variables (i.e. %HADOOP_COMMON_HOME%), and it does not expand
> wildcards (i.e. lib/*.jar).
