> Non-lowercase field names in structs causes NullPointerException
> ----------------------------------------------------------------
>
> Key: HIVE-9107
> URL: https://issues.apache.org/jira/browse/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.
