Description

Impala needs a way to do introspection on the partition schema to give the use a reasonable "SHOW CREATE TABLE". For Hash bucketed tables this can be achieved, but for range partitioned tables it is not possible.

One solution would be to iterate over all the tablets and fetch the stop partition keys and extract the range component, however, this would require the PartitionSchema to have a method to decode a PartialRow from byte[].
