Subject Re: cqlsh problem
Date Tue, 20 Sep 2016 09:12:14 GMT
I am also getting the same error:
cqlsh <my host> -u cassandra -p cassandra

Connection error: ('Unable to connect to any servers', {'<my host>':
OperationTimedOut('errors=Timed out creating connection (5 seconds),
last_host=None',)})

But it is not consistent. Sometimes I manage to connect. It is random.
Using 2.1.14
