----------------------------------
Summary: Improvements Around CharTypeInfo
Key: HIVE-21264
URL: https://issues.apache.org/jira/browse/HIVE-21264
Project: Hive
Issue Type: Improvement
Affects Versions: 4.0.0, 3.2.0
Reporter: BELUGA BEHR
The {{CharTypeInfo}} stores the type name of the data type (char/varchar) and
the length (1-255). {{CharTypeInfo}} objects are often getting cached once
they are created.
The {hashcode()} and {{equals()}} of its sub-classes varchar and char are
inconsistent in this regard.
* Make hashcode and equals consistent (and fast)
* Simplify the {{getQualifiedName}} implementation and reduce the scope to
protected
* Other related nits
