[jira] [Updated] (HIVE-7765) Null pointer error with UNION ALL on
partitioned tables using Tez
[ https://issues.apache.org/jira/browse/HIVE-7765?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alex Bush updated HIVE-7765:
----------------------------
Affects Version/s: 0.14.0
> Null pointer error with UNION ALL on partitioned tables using Tez
> -----------------------------------------------------------------
>
> 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.
> 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;
