-------------------------------
Assignee: tartarus
> FileSinkOperator thows NullPointerException
> --------------------------------------------
>
> Key: HIVE-18412
> URL: https://issues.apache.org/jira/browse/HIVE-18412
> Project: Hive
> Issue Type: Bug
> Components: Hive, Transactions
> Environment: HDP2.6.1, Hive 1.2.1
> Reporter: Benjamin BONNET
> Assignee: tartarus
> Priority: Blocker
>
> 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.
