public abstract class QueryConsistencyException
extends QueryExecutionException
implements CoordinatorException

A failure to reach the required consistency level during the execution of a query.

Such an exception is returned when the query has been tried by Cassandra but cannot be achieved with the requested consistency level because either:

• the coordinator did not receive enough replica responses within the rpc timeout set for Cassandra;
• some replicas replied with an error.

Method Detail

getConsistencyLevel

public ConsistencyLevel getConsistencyLevel()

The consistency level of the operation that failed.

Returns:

the consistency level of the operation that failed.

getReceivedAcknowledgements

public int getReceivedAcknowledgements()

The number of replicas that had acknowledged/responded to the operation before it failed.

Returns:

the number of replica that had acknowledged/responded the operation before it failed.

getRequiredAcknowledgements

public int getRequiredAcknowledgements()

The minimum number of replica acknowledgements/responses that were required to fulfill the operation.

Returns:

The minimum number of replica acknowledgements/response that were required to fulfill the operation.

getEndPoint

public EndPoint getEndPoint()

The connection information of the coordinator host that was contacted. May be null if the coordinator is not known.

Note that this is the information of the host that coordinated the query, not the one that timed out.

Specified by:

getEndPoint in interface CoordinatorException

getAddress

@Deprecated
public InetSocketAddress getAddress()

Deprecated.

Description copied from interface: CoordinatorException

The full address of the coordinator host that was contacted; may be null if the coordinator is not known.

Specified by:

getAddress in interface CoordinatorException

getHost

@Deprecated
public InetAddress getHost()

Deprecated.

Description copied from interface: CoordinatorException

The coordinator host that was contacted; may be null if the coordinator is not known.

Specified by:
