------------------------------------
Summary: Better exception when files are unaccessible
Key: PARQUET-20
URL: https://issues.apache.org/jira/browse/PARQUET-20
Project: Parquet
Issue Type: Bug
Reporter: Julien Le Dem
In some cases the Hadoop filesystem API will throw NullPointerException when
trying to access files that have moved.
We'd want to catch those and give a better error message.
