---------------------------------------
Summary: pyspark unable to create UDF: java.lang.RuntimeException:
org.apache.hadoop.fs.FileAlreadyExistsException: Parent path is not a
directory: /tmp tmp
Key: SPARK-17143
URL: https://issues.apache.org/jira/browse/SPARK-17143
Project: Spark
Issue Type: Bug
Components: PySpark
Affects Versions: 1.6.1
Environment: spark version: 1.6.1
python version: 3.4.3 (default, Apr 1 2015, 18:10:40)
[GCC 4.8.2 20140120 (Red Hat 4.8.2-16)]
Reporter: Andrew Davidson
For unknown reason I can not create UDF when I run the attached notebook on my
cluster. I get the following error
Py4JJavaError: An error occurred while calling
None.org.apache.spark.sql.hive.HiveContext.
: java.lang.RuntimeException: org.apache.hadoop.fs.FileAlreadyExistsException:
Parent path is not a directory: /tmp tmp
The notebook runs fine on my Mac
In general I am able to run non UDF spark code with out any trouble
I start the notebook server as the user “ec2-user" and uses master URL
spark://ec2-51-215-120-63.us-west-1.compute.amazonaws.com:6066
I found the following message in the notebook server log file. I have log level
set to warn
16/08/18 21:38:45 WARN ObjectStore: Version information not found in metastore.
hive.metastore.schema.verification is not enabled so recording the schema
version 1.2.0
16/08/18 21:38:45 WARN ObjectStore: Failed to get database default, returning
NoSuchObjectException
The cluster was originally created using spark-1.6.1-bin-hadoop2.6/ec2/spark-ec2
