> Key: HIVE-10621

> Project: Hive
> Issue Type: Bug
> Components: Serializers/Deserializers

> correct equals method implementation should start with
> {code}
> if (this == other) {
> return true;
> }
> if (other == null || getClass() != other.getClass()) {
> return false;
> }
> {code}
> DecimalTypeInfo, PrimitiveTypeInfo, VarcharTypeInfo, CharTypeInfo,
> HiveDecimalWritable equals method implementation starts with
> {code}
> if (other == null || !(other instanceof <class_name>)) {
> return false
> }
> {code}
> - first of all check for null is redundant
> - the second issue is that "other instanceof <class_name>" check is not
> symmetric.
> contract of equals() implies that, a.equals(b) is true if and only if
> b.equals(a) is true
> Current implementation violates this contract.
> e.g.
> DecimalTypeInfo instanceof PrimitiveTypeInfo is true
> but
> PrimitiveTypeInfo instanceof DecimalTypeInfo is false
> See more details here
