John Sichi commented on HIVE-976:
---------------------------------
Regarding input40.q: yes, I get a diff because the results from this query
come out in a different order:
select * from tmp_insert_test_p where ds = '2009-08-01';
A big chunk of rows moves in the output. Diff-based testing doesn't really
work if it's not possible to add order by uniformly, does it?
> test outputs should compare the file/directory for sampling

> Currently, all lines starting with file: are ignored.
> It means that
> file:/Users/heyongqiang/Documents/workspace/Hive-Test/build/ql/test/data/warehouse/srcbucket/srcbucket0.txt
> [s]
> and
> file:/Users/heyongqiang/Documents/workspace/Hive-Test/build/ql/test/data/warehouse/srcbucket
> [s]
> are same - that is not good because it will hide some of the optimizations of
> sampling.
> This should be changed to compare the last token.
