Change subject: IMPALA-5525 Extend TestScannersFuzzing to test uncompressed parquet

Patch Set 1:

File tests/query_test/

Line 68
Avoid unrelated whitespace diffs.

One way of getting a graphical diff that can help with this is to use the tool meld. For example:

git difftool -y -t meld <branch> <file>

Where <branch> could be asf-gerrit/master or origin/master or whatnot.

PS1, Line 96:     fq_tbl_name = "functional_parquet" + "." + tbl_name
I'm wary of creating tables in our default schemas. This won't get cleaned up, and it is subtle
behavior. If we can create the new table in the unique_database that would be nice

PS1, Line 98:     create = ("create table {0} stored as parquet as select * from functional.alltypes"
            :               .format(fq_tbl_name))
I think we need to verify that the right options are being set when we create this table.
As I understand it, you need to specify the query option compression_codec = none to create
a parquet file without compression.
