Subject [jira] [Created] (CASSANDRA-14220) C* returns to the driver NullPointerException sometimes when creating a keyspace
Date Wed, 07 Feb 2018 17:59:00 GMT
Jaume M created CASSANDRA-14220:
-----------------------------------

             Summary:  C* returns to the driver NullPointerException sometimes when creating
a keyspace
                 Key: CASSANDRA-14220
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14220
             Project: Cassandra
          Issue Type: Bug
         Environment: C* version: 3.11.1
            Reporter: Jaume M
         Attachments: node1_system.log, node2_system.log, node3_system.log

This happening regular on the python driver CI and it's reasonable to assume that C* is under
heavy load when it happens. The CQL command sent is
{code}
CREATE KEYSPACE keyspace WITH replication " = {'class': 'SimpleStrategy', 'replication_factor':
1}
{code}
or 
{code}
CREATE TABLE table_name (k INT, i INT, PRIMARY KEY(k, i))
{code}

The error the driver gets is
{code}
<Error from server: code=0000 [Server error] message="java.lang.RuntimeException: java.util.concurrent.ExecutionException:
java.lang.NullPointerException">
{code}
