> This JIRA is loosely related with SPARK-21573. Python 2.6 could be used in
> Jenkins given the past cases and investigations up to my knowledge and it
> looks failing to execute some other scripts.
> In this particular case, it was:
> {code}
> cd dev && python2.6
> {code}
> {code}
> >>> from sparktestsupport import shellutils
> >>> shellutils.subprocess_check_call("ls")
> Traceback (most recent call last):
> File "<stdin>", line 1, in <module>
> File "sparktestsupport/shellutils.py", line 46, in subprocess_check_call
> retcode = call(*popenargs, **kwargs)
> NameError: global name 'call' is not defined
> {code}
> Please see
> https://amplab.cs.berkeley.edu/jenkins/job/NewSparkPullRequestBuilder/3950/console
> Since we dropped the Python 2.6.x support, looks better we remove those
> workarounds and print out explicit error messages in order to duplicate the
> efforts to find out the root causes for such cases.
