-------------------------------
Summary: Fix BundleJarExample NPE and BundleJarRunner
Key: TWILL-77
URL: https://issues.apache.org/jira/browse/TWILL-77
Project: Apache Twill
Issue Type: Bug
Components: ext
Affects Versions: 0.3.0-incubating
Reporter: Alvin Wang
Assignee: Alvin Wang
>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.
