Java Gateway does not log through logger

[dcontador]

Some Java Gateway messages are logged using the logging module directly, hence those messages ignore logging level set for py4j.

Particularly happens when any Python script using Spark (2.4.7 in Windows) closes, provoking one or more exceptions that cannot be hidden configuring the py4j logger:

ERROR:root:Exception while sending command.
Traceback (most recent call last):
File "C:\CESADAR\ATAVIA\PYTHON\lib\site-packages\py4j\java_gateway.py", line 1152, in send_command
answer = smart_decode(self.stream.readline()[:-1])
File "C:\CESADAR\ATAVIA\PYTHON\lib\socket.py", line 589, in readinto
return self._sock.recv_into(b)
ConnectionResetError: [WinError 10054] Se ha forzado la interrupción de una conexión existente por el host remoto

During handling of the above exception, another exception occurred:
