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.
