--------------------------------------
Summary: Type.hashCode() takes originalType into account but
Type.equals() does not
Key: PARQUET-1191
URL: https://issues.apache.org/jira/browse/PARQUET-1191
Project: Parquet
Issue Type: Bug
Reporter: Zoltan Ivanfi
If two Type instances are equal according to equals() but have different
logical types, then both of the following cases are possible:
* The two instances may accidentally have the same hash, which is consistent
with the equals() method but is pure coincidence and has a very low
probablility.
* The two instances may have different hashes and end up in different buckets
of a hash map, leading to a situation where we can't find a value in the hash
map despite that it's equals() would return true.
