It's a bug in ColumnAccessAnalyzer. I've booked this on https://issues.apache.org/jira/browse/HIVE-6910.
Thanks, Navis 2014-04-15 11:41 GMT+09:00 Adeel Qureshi <adeelmahm...@gmail.com>: > I am trying to read the columns from hive queries being executed by > implementing the ExecuteWithHookContext hook. This works fine by extracting > ColumnAccessInfo information from HiveContext (which is passed in) > .getQueryPlan().getColumnAccessInfo(). This provides access to a > TableToColumnAccessMap which has all the columns from the query in it along > with user information. So this works fine. > > However when I run same queries on partition tables the list of columns > returned by TableToColumnAccessMap are not correct. It includes the > partition columns but ends up excluding some of the non-partioned columns. > So for a 5 column table with last 2 being partitioned columns it would > return 1 non-partioned and 2 partioned columns and simply ignore the other > two partitioned columns. Any ideas on what that might be the case or any > other ways on getting a handle on columns of a query being run. > > Thanks > Adeel
