Andrew Davidson created SPARK-11509:
---------------------------------------
Summary: ipython notebooks do not work on clusters created using
spark-1.5.1-bin-hadoop2.6/ec2/spark-ec2 script
Key: SPARK-11509
URL: https://issues.apache.org/jira/browse/SPARK-11509
Project: Spark
Issue Type: Bug
Components: Documentation, EC2, PySpark
Affects Versions: 1.5.1
Environment: AWS cluster
[ec2-user@ip-172-31-29-60 ~]$ uname -a
Linux ip-172-31-29-60.us-west-1.compute.internal 3.4.37-40.44.amzn1.x86_64 #1
SMP Thu Mar 21 01:17:08 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
Reporter: Andrew Davidson
I recently downloaded spark-1.5.1-bin-hadoop2.6 to my local mac.
I used spark-1.5.1-bin-hadoop2.6/ec2/spark-ec2 to create an aws cluster. I am
able to run the java SparkPi example on the cluster how ever I am not able to
run ipython notebooks on the cluster. (I connect using ssh tunnel)
According to the 1.5.1 getting started doc
http://spark.apache.org/docs/latest/programming-guide.html#using-the-shell
The following should work
PYSPARK_DRIVER_PYTHON=ipython PYSPARK_DRIVER_PYTHON_OPTS="notebook
--no-browser --port=7000" /root/spark/bin/pyspark
I am able to connect to the notebook server and start a notebook how ever
bug 1) the default sparkContext does not exist
from pyspark import SparkContext
textFile = sc.textFile("file:///home/ec2-user/dataScience/readme.md")
textFile.take(3
---------------------------------------------------------------------------
NameError Traceback (most recent call last)
<ipython-input-1-127b6a58d5cc> in <module>()
1 from pyspark import SparkContext
----> 2 textFile = sc.textFile("file:///home/ec2-user/dataScience/readme.md")
3 textFile.take(3)
NameError: name 'sc' is not defined
bug 2)
If I create a SparkContext I get the following python versions miss match error
sc = SparkContext("local", "Simple App")
textFile = sc.textFile("file:///home/ec2-user/dataScience/readme.md")
textFile.take(3)
File "/root/spark/python/lib/pyspark.zip/pyspark/worker.py", line 64, in main
("%d.%d" % sys.version_info[:2], version))
Exception: Python in worker has different version 2.7 than that in driver 2.6,
PySpark cannot run with different minor versions
I am able to run ipython notebooks on my local Mac as follows. (by default you
would get an error that the driver and works are using different version of
python)
$ cat ~/bin/pySparkNotebook.sh
#!/bin/sh
set -x # turn debugging on
#set +x # turn debugging off
export PYSPARK_PYTHON=python3
export PYSPARK_DRIVER_PYTHON=python3
IPYTHON_OPTS=notebook $SPARK_ROOT/bin/pyspark $*$
I have spent a lot of time trying to debug the pyspark script however I can not
figure out what the problem is
Please let me know if there is something I can do to help
Andy
