Description

When running some tests of Mesos on Windows, I discovered that the following command would not execute successfully when passed to the Docker containerizer in TaskInfo.command:

python -c "print('hello world')"

The following error is found in the task sandbox:

  File "<string>", line 1
    "print('hello
                ^
SyntaxError: EOL while scanning string literal
