Richard Ding updated PIG-1489: ------------------------------ Attachment: PIG-1489.patch This patch adds registered jars to the class loader. > 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 > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
