> Null location Strings can cause problems with GroupedSplit serialization
> ------------------------------------------------------------------------
>
> Key: TEZ-2911
> URL: https://issues.apache.org/jira/browse/TEZ-2911
> Project: Apache Tez
> Issue Type: Bug
> Affects Versions: 0.5.0
> Reporter: Siddharth Seth
> Assignee: Siddharth Seth
> Attachments: TEZ-2911.1.txt, TEZ-2911.2.txt
>
>
> If the location is a non-null array, and one of the elements is null, and the
> GroupedSplit is the same as the raw split - the groupedSplit throws an NPE
> during serialization.
> This isn't necessarily a bug - since the original split location should not
> be null. However, there's parts of the code which ignore such null locations
> (and there's a test for this), while others don't. This should be done
> consistently.
