> 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
