Subject [jira] [Commented] (HIVE-3492) Provide ALTER for partition changing bucket number
Date Tue, 11 Dec 2012 04:03:24 GMT

Phabricator commented on HIVE-3492:
-----------------------------------

navis has commented on the revision "HIVE-3492 [jira] Provide ALTER for partition changing
bucket number".

  I tried to use 'alterStatementSuffixClusterbySortby' but it was not so simple.

  1. cannot make 'tableBuckets' have optional "cluster by" clause, which is used by create
DDL
  2. 'alterStatementSuffixClusterbySortby' accept table name only. To make it accept table
spec, still another definition would be needed

> As a follow up of HIVE-3283, bucket number of a partition could be set/changed individually
by query like 'ALTER table srcpart PARTIRION(ds='1999') SET BUCKETNUM 5'.
