> Project: Spark
> Issue Type: Improvement
> Components: Spark Core, SQL, Streaming
> Affects Versions: 1.3.1
> Reporter: Sean Owen
> Assignee: Sean Owen
> Priority: Minor
>
> Spark depends only on Commons Lang3 (3.x). However there are several
> accidental usages of Commons Lang (2.x) in the codebase. As we saw a few days
> ago the version of Lang 2.x that accidentally comes in via Hadoop can change
> with Hadoop version and so the accidental usage is more than a purely
> theoretical problem. It's easy to change the usages to 3.x counterparts.
> Also, there are just a few uses of Commons IO in the code which can be
> replaced with uses of Guava, removing another used but undeclared dependency.
