Subject [jira] [Commented] (SPARK-922) Update Spark AMI to Python 2.7
Date Sat, 04 Oct 2014 21:05:34 GMT

    [ https://issues.apache.org/jira/browse/SPARK-922?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14159284#comment-14159284
] 

Josh Rosen commented on SPARK-922:
----------------------------------

I chatted with someone who had a job that ran ~20x slower on Python 2.6 than on 2.7, likely
due to changes to the json library (in 2.7+, json is implemented as a C extension rather than
in pure-Python).  Maybe we should add a note on this to the docs.

> Many Python libraries only support Python 2.7+, so we should make Python 2.7 the default
Python on the Spark AMIs.
