Chinna Rao Lalam commented on HIVE-2512:
----------------------------------------
SemanticAnalyzer.genReduceSinkPlan() added a function validation check for
orderby and sortby in the same flow clusterby also executing so it is throwing
execption for the clusterby also.
Orderby and Sortby wont support the functions so need to add the function
validation check.
Now validation check is modified like it should check only for the orderby and
sortby.
Patch is uploaded and testcases are executing
> 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.
