Jeff Zhang commented on FLINK-17114:
------------------------------------
I think it depends what is the default python in your machine.
> When the pyflink job runs in local mode and the command "python" points to
> Python 2.7, the startup of the Python UDF worker will fail.

> When the PyFlink job runs in local mode and the command "python" points to
> Python 2.7, the startup of the Python UDF worker will fail because "python"
> is the default interpreter of the Python UDF worker. For this case we need to
> set the default value of "python.executable" to `sys.executable` i.e. the
> python interpreter which launches the job.
