-----------------------------------
Summary: 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
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.
