Key: HADOOP-8870
URL: https://issues.apache.org/jira/browse/HADOOP-8870
Project: Hadoop Common
Issue Type: Bug

Affects Versions: 1.0.3, 0.20.205.0
Reporter: Jaka Jancar
Reading
{code}s3n://bucket/{a/*,b/*,c/*}{code}
if one of the globs matches nothing, I get:
{code}
Exception in thread "main" java.lang.NullPointerException

I'm not sure whether this is specific to S3 or all filesystems.
This was occuring in 0.20.205 and I confirmed it's still present in 1.0.3.
