Every time when I use the VanillaWindowsProcess on AWS the following error message appears:
No handlers could be found for logger "_socket"
How I can fix this?
For WinRM, Brooklyn 0.8.0 is using winrm4j which currently uses pywinrm via jython version 2.7-b3.
The error you encountered is coming from jython: described at http://bugs.jython.org/issue2253, and a fix (within python code) at https://hg.python.org/jython/rev/e37122c32d8a.
I suspect a workaround would be to execute a similar thing in jython:
log = logging.getLogger("_socket")
log.setLevel(level=logging.WARNING)
The long-term solution is to fix it in winrm4j - I've created an issue for this - https://github.com/cloudsoft/winrm4j/issues/5.
(There is a proposal to re-write winrm4j in pure Java, but that hasn't been done yet).
I presume this error is benign (i.e. everything else still works)?
Or is the attempt to log an indication that there was a different problem (whose details unfortunately don't reach the log or the console!)?
