Date Tue, 16 Dec 2014 08:58:13 GMT


Lefty Leverenz commented on HIVE-9107:

Is this related to HIVE-8386 or HIVE-8870 (also HIVE-6198)?

>    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
> 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.
