Hi Guys,
I am some problems of Connection Timeout in a random mode, that is, the
application in python that I am using sometimes it does work very well
sometimes not, I am getting this error:
015-10-28 19:49:05,286 [WARNING] cassandra.cluster: [control connection] Error
connecting to 10.20.255.191:

NoHostAvailable: ('Unable to connect to any servers', {'10.20.255.191':

I have had some tests with others applications in python and the same error
occur. Does anyone have any idea?
Thanks a lot
