--------------------------------------
Summary: Add a note that 'hash x range' and 'range x hash'
partition for Kudu tables produce the same result
Key: IMPALA-10457
URL: https://issues.apache.org/jira/browse/IMPALA-10457
Project: IMPALA
Issue Type: Documentation
Components: Docs
Reporter: Alexey Serbin
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|https://issues.apache.org/jira/browse/IMPALA-7686].
With knowledge on Kudu partitioning its self-obvious that 'hash x range' and
'range x hash' should result in the same result, but it's 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
