> Pig 0.15 stopped working with Hadoop 1.x
> ----------------------------------------

> Key: PIG-4592
> URL: https://issues.apache.org/jira/browse/PIG-4592
> Project: Pig
> Issue Type: Bug
> Components: build
> Affects Versions: 0.15.0
> Environment: Hadoop 1.x and pig.jar retrieved from Maven
> Reporter: Costin Leau
> Assignee: Daniel Dai
> Priority: Blocker
> Fix For: 0.15.0
>
> Attachments: PIG-4592-1.patch

>
> It looks like the Maven jar for Pig 0.15 is built against Hadoop 1.x instead
> of Hadoop 2.x.
> Running Pig 0.15 against a Hadoop 1 environment (which works fine in 0.14)
> triggers a storm of class not found exceptions for classes in Hadoop 2 (like
> org/apache/hadoop/mapreduce/task/JobContextImpl).
> The culprit seems to be the HadoopShim included in 0.15 which is different
> from 0.14 (and previous) - it's part of hadoop23 instead of hadoop20 package
> (whatever that means).
> As it stands right now, using Pig 0.15 from Maven (common case) with Hadoop
> 1.x is impossible.
