Description
System details :
- Client is 172.23.100.204
- cd /root/CASSANDRA-YCSB/YCSB_3
- run jdbcload.sh
Server :
1. server is 172.23.100.190
2. CB version 4.5.1
The problem here is that the ycsb client sends this query to JDBC:
INSERT INTO usertable (YCSB_KEY,field1,field0,field7,field6,field9,field8,field3,field2,field5,field4) VALUES(?,?,?,?,?,?,?,?,?,?,?)
This statement is correct SQL but not correct N1QL. The Simba driver tries to prepare this statement by converting it into this statement, as though it were N1QL:
prepare INSERT INTO usertable (YCSB_KEY,field1,field0,field7,field6,field9,field8,field3,field2,field5,field4) VALUES(?,?,?,?,?,?,?,?,?,?,?)
This is not correct N1QL. The Simba driver should convert the original statement to N1QL and then prepend a "prepare".
Here is the log output:

I will file a ticket with Simba for this problem.
