Review request for drill and Steven Phillips.
Bugs: DRILL-2842
https://issues.apache.org/jira/browse/DRILL-2842
Repository: drill-git
Description
-------
Parquet files with large footers could not be read. The length of the footer is
written at the end of the file. To avoid excessive reads for smaller files, we
read a reasonable amount of the end of the file that may contain the whole
footer, with the actual exact length appearing at the end of the read. After
checking the length we tried to read the remining portion ahead of what was
already read and splice them together. The offset for where to put the bytes
read first was off.
