Cassandra Error Code List

Question

When using the datastax node.js driver, I get an exception code as described in http://docs.datastax.com/en/developer/nodejs-driver-dse/1.4/api/module.errors/class.ResponseError/ .

However, I cannot find documentation about all available exception codes. Does anyone know where to find it?

Answer 1

I'm not sure that the code values ​​are listed anywhere, but you can always look at the source of ExceptionCode for the version from Cassandra that you are working with.

In trunk this errors are listed as:

SERVER_ERROR    (0x0000),
PROTOCOL_ERROR  (0x000A),

BAD_CREDENTIALS (0x0100),

// 1xx: problem during request execution
UNAVAILABLE         (0x1000),
OVERLOADED          (0x1001),
IS_BOOTSTRAPPING    (0x1002),
TRUNCATE_ERROR      (0x1003),
WRITE_TIMEOUT       (0x1100),
READ_TIMEOUT        (0x1200),
READ_FAILURE        (0x1300),
FUNCTION_FAILURE    (0x1400),
WRITE_FAILURE       (0x1500),
CDC_WRITE_FAILURE   (0x1600),

// 2xx: problem validating the request
SYNTAX_ERROR    (0x2000),
UNAUTHORIZED    (0x2100),
INVALID         (0x2200),
CONFIG_ERROR    (0x2300),
ALREADY_EXISTS  (0x2400),
UNPREPARED      (0x2500);
