------------------------------------------------------------------

I checked my CentOS box, and it has:

{noformat}
  -p DIR, --tmpdir[=DIR]  interpret TEMPLATE relative to DIR; if DIR is not
                        specified, use $TMPDIR if set, else /tmp.  With
                        this option, TEMPLATE must not be an absolute name;
                        unlike with -t, TEMPLATE may contain slashes, but
                        mktemp creates only the final component
  -t                  interpret TEMPLATE as a single file name component,
                        relative to a directory: $TMPDIR, if set; else the
                        directory specified via -p; else /tmp [deprecated]
{noformat}

> h3. Description of Issue
> * What did you expect to happen?
> In the {{__enter__}} method in the {{SSHTempFileContent}} class ({{ssh_execute_operator.py}})
a file should be created using {{mktemp}}
> * What happened instead?
> The call to mktemp fails, because the {{--tmpdir}} command line option is not supported
in OSX
> (see https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man1/mktemp.1.html)
> * Stack trace, if appropriate:
> {noformat}
> [2016-05-18 17:39:31,735] {models.py:1144} ERROR - Failed to create remote temp file
> Traceback (most recent call last):
>   File "/Users/rlanda/.virtualenvs/datapath-airflow/bin/airflow", line 15, in <module>
>     args.func(args)
>   File "/Users/rlanda/.virtualenvs/datapath-airflow/lib/python2.7/site-packages/airflow/bin/cli.py",
line 316, in test
>     ti.run(force=True, ignore_dependencies=True, test_mode=True)

>     result = task_copy.execute(context=context)
>   File "/Users/rlanda/.virtualenvs/datapath-airflow/lib/python2.7/site-packages/airflow/contrib/operators/ssh_execute_operator.py",

line 52, in __enter__
>     raise AirflowException("Failed to create remote temp file")
> airflow.utils.AirflowException: Failed to create remote temp file
> {noformat}
> The stack trace is not very useful. However looking at the tuple returned by {{pmktemp.communicate()}}
is helpful:
> {noformat}
> mktemp: illegal option -- -
> usage: mktemp [-d] [-q] [-t prefix] [-u] template ...
>        mktemp [-d] [-q] [-u] -t prefix 
> {noformat}
> h3. Reproducing the Issue
> Issue happens with normal usage of {{SSHHook}} when attempting to run commands on an
OSX box.
> h3. Fix
> Changing {{--tmpdir}} by {{-t}} seems to fix the issue in OSX, but I do not have access
to a linux box to check if it breaks there.
