>
> On Windows, FileUtil.createJarWithClassPath() is called to generate a
> manifest jar file to pack classpath - to avoid the problem of classpath being
> too long.
> However, the relative classpath is not handled correctly. It relies on Java's
> File(relativePath) to resolve the relative path. But it really should be
> using the given pwd parameter to resolve the relative path.
> To reproduce this bug, you can try some pig job on Windows, it will fail and
> the pig log on the application master will look like this:
> 2013-08-29 23:25:55,498 INFO [main]
> org.apache.hadoop.service.AbstractService: Service
> org.apache.hadoop.mapreduce.v2.app.MRAppMaster failed in state INITED; cause:
> org.apache.hadoop.yarn.exceptions.YarnRuntimeException:
> java.lang.RuntimeException: java.lang.ClassNotFoundException: Class
> org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.PigOutputFormat
> not found
> org.apache.hadoop.yarn.exceptions.YarnRuntimeException:
> java.lang.RuntimeException: java.lang.ClassNotFoundException: Class
> org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.PigOutputFormat
> not found
> This is because the PigOutputFormat class is in the job.jar file but the
> classpath manifest has:
> file:/c:/apps/dist/hadoop-2.1.0-beta/bin/job.jar/job.jar
> When it really should be:
> file:/<job container folder>/job.jar/job.jar
