> Key: SPARK-16253
> URL: https://issues.apache.org/jira/browse/SPARK-16253
> Project: Spark
> Issue Type: Task
> Components: SQL
> Affects Versions: 1.6.2
> Reporter: zenglinxi
>
> Some hive sql like:
> {quote}
> add file /tmp/spark_sql_test/test.py;
> select transform(cityname) using 'test.py' as (new_cityname) from test.spark2_orc where dt='20160622' limit 5 ;
> {quote}
> can't be executed by spark sql directly, since it will return error like:
> {quote}
> 16/06/26 11:01:28 INFO codegen.GenerateUnsafeProjection: Code generated in 19.054534 ms
> 16/06/26 11:01:28 ERROR execution.ScriptTransformationWriterThread: /bin/bash: test.py: command not found
> {quote}
> and the sql works fine in hive with MR.
> Lots of ETL can't be moved from hive to spark sql because of this problem.
