> Key: GEODE-2129

> Project: Geode
> Issue Type: Bug
> Components: serialization

> Right now pdxtype id has 4 bytes. Out of those 4 bytes, one byte reserved
> for distributed-system-id, this make sure type id generated from different
> cluster has different id. For rest of the three bytes we just increment
> counter to create new pdxtype id. In the field, we have observed that
> sometimes this pdxType Id collides. One reason could be they end up having
> same distributed-system-id for the different cluster.
> Thus to avoid a collision, we will be using hashcode of pdxType for three
> bytes of pdxType id. That will reduce the possibility of collision.
