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
