Description
I stumbled upon on a fact that in Impala prior to version 4 the syntax for CREATE TABLE doesn't allow specifying range x hash partition, the only acceptable syntax is hash x range, as reflected in IMPALA-7686.
With knowledge on Kudu partitioning, it's rather self-obvious that hash x range and range x hash should result in the same layout of data across Kudu tablets, but it would be great to explicitly document that (probably, with the reference to this page https://kudu.apache.org/docs/schema_design.html#hash-range-partitioning-example ?).
Probably, the best place to add the note is: https://impala.apache.org/docs/build/html/topics/impala_kudu.html#ariaid-title17
