Subject [jira] [Created] (HIVE-9107) Non-lowercase field names in structs causes NullPointerException
Date Mon, 15 Dec 2014 21:18:13 GMT
Jim Pivarski created HIVE-9107:

             Summary: Non-lowercase field names in structs causes NullPointerException
                 Key: HIVE-9107
             Project: Hive
          Issue Type: Bug
    Affects Versions: 0.13.1
            Reporter: Jim Pivarski

If an HQL query references a struct field with mixed or upper case, Hive throws a NullPointerException
instead of giving a better error message or simply lower-casing the name.

For example, if I have a struct in column mystruct with a field named myfield, a query like

select mystruct.MyField from tablename;

passes the local initialize (it submits an M-R job) but the remote initialize jobs throw NullPointerExceptions.
 The exception is on line 61 of org.apache.hadoop.hive.ql.exec.ExprNodeFieldEvaluator, which
is right after the field name is extracted and not forced to be lower-case.
