Dong Chen commented on HIVE-9442:
---------------------------------
Work procedure is:
1. run existed file format(ORC, etc) test cases for Parquet non-vectorized. Fix
bugs and add tests if any.
2. run existed vectorized(ORC) test cases for Parquet. Fix bugs and add tests
if any. (The on-going Parquet Vectorization work may introduce change when it's
done. But I think we can still do this check now. They are relatively
independent and we could see and make change at that time.)
3. make the coverage of vectorized test cases for Parquet about data types
compelte.
The goal is to make all data types (except DATE, not implemented yet) work for
non-vectorized & vectorized Parquet.
> Make sure all data types work for PARQUET

> In HIVE-9235 (Turn off Parquet Vectorization until all data types work:
> DECIMAL, DATE, TIMESTAMP, CHAR, and VARCHAR), some data types were found not
> work for PARQUET.
> Work in this Jira will find the root cause, fix it, and add tests for them.
