File 
testdata/workloads/functional-query/queries/QueryTest/parquet-resolution-by-name.test:

Line 22: aaaaaaa','bbbbbbb'
       : 'ccccc','dddd'
       : 'eeeeeeee','f'
shouldn't the result column 1 and column 2 swap here?
or the alter statement doesn't make any difference?


Line 28: alter table resolution_by_name_test change a new_a string;
do we start a new session for each query test here?
If not, the following query will be run with "parquet_resolve_by_name=1", 
right? (until we reset it back to 0)


Line 53: drop table if exists nested_resolution_by_name_test;
       : create table nested_resolution_by_name_test like complextypestbl
would this work if the test is run concurrently in exhaustive mode for various 
file format?


Line 148: rename nested field
do we also give warning why impala returns NULL?
so user knows what's wrong.
