Description

This issue is based on a discussion on the list started by dweeks

From the thread (he later provided a small repro file that is attached here):

Just wanted to see if you or anyone else has run into problems reading
files after the ByteBuffer patch. I've been running into issues and have
narrowed it down to the ByteBuffer commit using a small repro file (written
with 1.6.0, unfortunately can't share the data).

It doesn't happen for every file, but those that fail give this error:

can not read class org.apache.parquet.format.PageHeader: Required field
'uncompressed_page_size' was not found in serialized data! Struct:
PageHeader(type:null, uncompressed_page_size:0, compressed_page_size:0)
