>                 Key: HIVE-7765
>                 URL: https://issues.apache.org/jira/browse/HIVE-7765
>             Project: Hive
>          Issue Type: Bug
>    Affects Versions: 0.14.0, 0.13.1
>         Environment: Tez 0.4.1, Ubuntu 12.04, Hadoop 2.4.1.
> Hadoop 2.2.6
>            Reporter: Chris Dragga
>            Priority: Minor
>
> When executing a UNION ALL query in Tez over partitioned tables where at least one table
is empty, Hive fails to execute the query, returning the message "FAILED: NullPointerException
null".  No stack trace accompanies this message.  Removing partitioning solves this problem,
as does switching to MapReduce as the execution engine.
> This can be reproduced using a variant of the example tables from the "Getting Started"
documentation on the Hive wiki.  To create the schema, use
> CREATE TABLE invites (foo INT, bar STRING) PARTITIONED BY (ds STRING);
> CREATE TABLE empty_invites (foo INT, bar STRING) PARTITIONED BY (ds STRING);
> Then, load invites with data (e.g., using the instructions [here|https://cwiki.apache.org/confluence/display/Hive/GettingStarted#GettingStarted-DMLOperations])
and execute the following:
> SELECT * FROM invites
> UNION ALL
> SELECT * FROM empty_invites;
