Write Timeout error in Cassandra using python cassandra driver

Question

I have a single node cluster and when I perform the following query, I get the following error,

DELETE FROM issuetable WHERE "partitionId"='1';

**

• Error:

** :

WriteTimeout: Error from server: code=1100 [Coordinator node timed 
out waiting for replica nodes' responses] message="Operation timed out 
- received only 0 responses." info={'received_responses': 0, 
'required_responses': 1, 'consistency': 'QUORUM'}

As per datastax document (https://datastax.github.io/python-driver/api/cassandra.html), they mentioned increasing the write_request_timeout_in_ms in the cassandra.yaml

Question :

1) Why I get this error? As per my table (issuetable) I have only 84 entries under that partition.

2) Should this be solved client-side or server-side?
