SERVER_ERROR = Something unexpected happened. This indicates a server-side bug.

0x0000

PROTOCOL_ERROR = Some client message triggered a protocol violation (for instance a QUERY message is sent before a STARTUP one has been sent).

0x000A

BAD_CREDENTIALS = CREDENTIALS request failed because Cassandra did not accept the provided credentials.

0x0100

UNAVAILABLE = Unavailable exception. Details: :cl - The consistency level of the query having triggered the exception. :required - An int representing the number of nodes that should be alive to respect :cl. :alive - An int representing the number of replica that were known to be alive when the request has been processed (since an unavailable exception has been triggered, there will be :alive < :required.

0x1000

OVERLOADED = The request cannot be processed because the coordinator node is overloaded.

0x1001

IS_BOOTSTRAPPING = The request was a read request but the coordinator node is bootstrapping.

0x1002

TRUNCATE_ERROR = Error during a truncation error.

0x1003

WRITE_TIMEOUT = Timeout exception during a write request. Details: :cl - The consistency level of the query having triggered the exception. :received - An int representing the number of nodes having acknowledged the request. :blockfor - The number of replica whose acknowledgement is required to achieve :cl. :write_type - A string that describe the type of the write that timeouted. The value of that string can be one of: "SIMPLE": the write was a non-batched non-counter write. "BATCH": the write was a (logged) batch write. If this type is received, it means the batch log has been successfully written (otherwise a "BATCH_LOG" type would have been send instead). "UNLOGGED_BATCH": the write was an unlogged batch. Not batch log write has been attempted. "COUNTER": the write was a counter write (batched or not). "BATCH_LOG": the timeout occured during the write to the batch log when a (logged) batch write was requested.

0x1100

READ_TIMEOUT = Timeout exception during a read request. Details: :cl - The consistency level of the query having triggered the exception :received - An int representing the number of nodes having answered the request. :blockfor - The number of replica whose response is required to achieve :cl. Please note that it is possible to have :received >= :blockfor if :data_present is false. And also in the (unlikely) case were :cl is achieved but the coordinator node timeout while waiting for read-repair acknowledgement. :data_present - If true, it means the replica that was asked for data has not responded.

0x1200

SYNTAX_ERROR = The submitted query has a syntax error.

0x2000

UNAUTHORIZED = The logged user doesn't have the right to perform the query.

0x2100

INVALID = The query is syntactically correct but invalid.

0x2200

CONFIG_ERROR = The query is invalid because of some configuration issue.

0x2300

ALREADY_EXISTS = The query attempted to create a keyspace or a table that was already existing. Details: :ks - A string representing either the keyspace that already exists, or the keyspace in which the table that already exists is. :table - A string representing the name of the table that already exists. If the query was attempting to create a keyspace, :table will be present but will be the empty string.

0x2400

UNPREPARED = Can be thrown while a prepared statement tries to be executed if the provide prepared statement ID is not known by this host. Details: :id - The unknown ID.

0x2500
