>                 Key: SPARK-26105
>                 URL: https://issues.apache.org/jira/browse/SPARK-26105
>             Project: Spark
>          Issue Type: Test
>          Components: PySpark
>    Affects Versions: 3.0.0
>            Reporter: Hyukjin Kwon
>            Priority: Major
>
> Currently, PySpark tests sill assume the tests could be ran in Python 2.6 by importing {{unittest2}}. For instance:
> {code}
> if sys.version_info[:2] <= (2, 6):
>     try:
>         import unittest2 as unittest
>     except ImportError:
>         sys.stderr.write('Please install unittest2 to test with Python 2.6 or earlier')
>         sys.exit(1)
> else:
>     import unittest
> {code}
> We officially dropped Python 2.6 support a while ago and started to discuss about Python 2 drop. It's better to remove them out.
