Record fails to write
Records never appear in the DataStax Enterprise database table.
system.log
The location of the system.log file is:- /var/log/cassandra/system.log
Records never appear in the DataStax Enterprise (DSE) database table. The cause can be issues with node availability, transient errors that prevent writes due to consistency level, a schema change where a mapped column was removed from the target table, and so forth.
Remediation
Verify the following:
- Check for WARN and ERROR messages in the Kafka Connect log.
- Check for WARN and ERROR on the system.log on the DSE coordinator node.
- Status of writes. See Monitoring DataStax Apache Kafka Connector.
