I think keeping the "Stat" suffix is nice for having "HashPartitionStats" match the JSON. To make things symmetric, I've renamed "PartitionMetadata" back to "GenericPartitionStats". ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
