Hello Marcel Kornacker, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/4693 to look at the new patch set (#2). Change subject: IMPALA-3943: Do not throw scan errors for empty Parquet files. ...................................................................... IMPALA-3943: Do not throw scan errors for empty Parquet files. For Parquet files with no row groups but with num_rows=0 in the file footer the Parquet scanner returns an error indicating that the file is invalid. This behavior is a regression from previous Impala versions which used to accept such files. This patch restores the previous behavior and adds tests.
