> Project: Apache Twill

> From Alex Chin,
> 1. The bundle jar path (e.g. $HOME/my-app.jar) will be used as both the path
> to find the jar on the local filesystem and as the path to find the jar in
> the unpacked, localized archive from within YARN. So, without changing
> BundledJarExample or BundledJarRunner, the easiest way of meeting both these
> criteria is to make sure your bundle jar is in the current working directory.
> 2. BundledJarExample actually takes 4 mandatory arguments, not just 3. You
> must specify the ZooKeeper ensemble, the bundle jar, a library directory, and
> a main class. Once I added the library directory argument, it worked. It
> looks like BundledJarExample needs to be updated to match the arguments
> BundledJarRunner accepts.
> --
> Needed changes:
> 1. Instead of unpacking application jar and then adding both the original
> application jar and the jars within the libFolder directory inside the
> unpacked jar directory, BundledJarRunner should add ./, ./\*.jar, and
> ./lib/\*.jar within the unpacked jar directory to the classpath.
> 2. Remove required library directory argument from BundledJarExample and
> BundledJarRunner.
> 3. Add optional additional library directories to BundledJarRunner, in
> addition to ./\*.jar and ./lib/\*.jar.
> 4. Add better validations so that errors indicate a clear root cause.
