-----------------------------------
Looking into it
> 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. Also the query executes fine
> (with yarn) in spark-shell.
