Daniel Dai updated PIG-2239:
----------------------------
Attachment: PIG-2239-0.patch
Attach initial patch PIG-2239-0.patch. Some notes for the patch:
1. There is no change in java code, we still produce pig.jar,
pig-withouthadoop.jar. However, pig-withouthadoop.jar is more lightweight (no
hadoop dependencies, only Pig dependencies)
2. If HADOOP_HOME is defined, bin/pig will invoke hadoop runJar to run
pig-withouthadoop.jar, org.apache.pig.Main
3. If HADOOP_HOME is not defined, fall back to old way--link to bundled hadoop
20.2 libraries.
4. I didn't see any conflict options between Pig and Hadoop command line. The
only change is now pig command line support hadoop generic options which is not
supported before.
> Pig should use "bin/hadoop jar pig-withouthadoop.jar" in bin/pig instead of
> forming java command itself
