Bolke de Bruin created SPARK-8623:
-------------------------------------
Summary: Some queries in spark-sql lead to NullPointerException
when using Yarn
Key: SPARK-8623
URL: https://issues.apache.org/jira/browse/SPARK-8623
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.5.0
Environment: Hadoop 2.6, Kerberos
Reporter: Bolke de Bruin
The following query was executed using "spark-sql --master yarn-client" on
1.5.0-SNAPSHOT:
select * from wcs.geolite_city limit 10;
This lead to the following error:
15/06/25 09:38:37 WARN scheduler.TaskSetManager: Lost task 0.0 in stage 0.0
(TID 0, lxhnl008.ad.ing.net): java.lang.NullPointerException

This does not happen in every case, ie. some queries execute fine, and it is
unclear why.
Using just "spark-sql" the query executes fine as well and thus the issue seems
to rely in the communication with Yarn.
