----------------------------------
Summary: 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.
