Richard Ding updated PIG-1489:
------------------------------
Status: Patch Available (was: Open)
> Pig MapReduceLauncher does not use jars in register statement
> ---------------------------------------------------------------
>
> Key: PIG-1489
> URL: https://issues.apache.org/jira/browse/PIG-1489
> Project: Pig
> Issue Type: Bug
> Reporter: Olga Natkovich
> Assignee: Richard Ding
> Fix For: 0.8.0
>
> Attachments: PIG-1489.patch, PIG-1489.patch
>
>
> If my Pig StorFunc has its own OutputFormat class then Pig MapReducelauncher
> will try to instantiate it before
> launching the mapreduce job and fail with ClassNotFoundException.
> This happens because Pig MapReduce launcher uses its own classloader and
> ignores the classes in the jars in the
> register statement.
> The effect is that the jars not only have to be in "register " statement in
> the script but also in the pig
> classpath with the -classpath tag.
> This can be remedied by making the Pig MapReduceLauncher constructing a
> classloader that includes the registered jars
> and using that to instantiate the OutputFormat class.
