Subject HADOOP-13410
Date Tue, 09 Aug 2016 16:00:34 GMT
I'd like to get feedback from the community (especially those who might
remember this) on HADOOP-13410:
https://issues.apache.org/jira/browse/HADOOP-13410

It appears that Hadoop's RunJar adds the original jar to the app's
classpath even though the unjarred contents of the jar are in the
classpath. As long as the file is a jar (or its variant), this seems
completely superfluous. My suspicion is that the line of code that adds the
jar to the classpath may have been left there by accident.

Could anyone confirm this? Does anyone see an issue with removing the jar
from the classpath? I've tested the fix with a couple of simple apps, and I
didn't see a problem.

Thanks,
Sangjin
