Subject [jira] Created: (HIVE-238) complex columns are not handled properly in cluster by, distributed by, sort by clauses and in some select clauses

complex columns are not handled properly in cluster by, distributed by, sort by clauses and
in some select clauses
------------------------------------------------------------------------------------------------------------------

                 Key: HIVE-238
                 URL: https://issues.apache.org/jira/browse/HIVE-238
             Project: Hadoop Hive
          Issue Type: Bug
          Components: Query Processor
            Reporter: Prasad Chakka


if a column is complex then the sub fields can't be referenced in cluster by, distributed
by, sort by clauses

for example if column c1 is an object with attributes a and b then the following query returns
an error

select * from t1 cluster by t1.c1.a (or similar queries)

also the following query will return an error because current code doesn't distinguish between
a complex column or a table alias.

select c1.a from t1
