> Hi,
> while executing a query (DELETE with a join) on an ACID table, I get a NullPointerException in reducer.
> See stack trace below.
> According to FileSinkOperator source code, it seems that buckepMap transient field is Null.
> In my opinion, the only circumstance in which this field may be null is when the involved FileSinkOperator has been serialized and then deserialized. Actually, deserialization lets that transient reference uninitialized.
> I checked source code for more recent versions (including Hive 2.x) but everywhere that field may remain uninitialized (if FileSinkOperator is serialized/deserialized). So I think that issue may concern any version of Hive.
