Ning Zhang commented on HIVE-2512:
----------------------------------
Chinna, the Hive wiki may only say it requires column names, but I think the
syntax Hive.q may allow functions in orderby/sortby.
At the same time, would you mind upload a patch to revert HIVE-2145 first?
Without reverting it, it breaks backward compatibility and have introduced some
problems in our production.
> After HIVE-2145, Hive disallow any use of function in cluster-by clause

> After HIVE-2145, the following query returns a semantic analysis error:
> FROM src SELECT * cluster by rand();
> FAILED: Error in semantic analysis: functions are not supported in order by
> Looking back at HIVE-2145, it's clear that the patch is more restrictive than
> necessary.
> Chinna, are you able to work on it? Please let me know if you don't have
> cycles to do it now.
