removeNode

public void removeNode(java.lang.String hostIdString)

Remove a node that has died, attempting to restore the replica count. If the node is alive, decommission should be attempted. If decommission fails, then removeToken should be called. If we fail while trying to restore the replica count, finally forceRemoveCompleteion should be called to forcibly remove the node without regard to replica count.

Specified by:

removeNode in interface StorageServiceMBean

Parameters:

hostIdString - token for the node

drain

public void drain()
           throws java.io.IOException,
                  java.lang.InterruptedException,
                  java.util.concurrent.ExecutionException

Shuts node off to writes, empties memtables and the commit log. There are two differences between drain and the normal shutdown hook: - Drain waits for in-progress streaming to complete - Drain flushes *all* columnfamilies (shutdown hook only flushes non-durable CFs)

Specified by:

drain in interface StorageServiceMBean

Throws:

java.io.IOException

java.lang.InterruptedException

java.util.concurrent.ExecutionException

truncate

public void truncate(java.lang.String keyspace,
            java.lang.String columnFamily)
              throws java.util.concurrent.TimeoutException,
                     java.io.IOException

Description copied from interface: StorageServiceMBean

Truncates (deletes) the given columnFamily from the provided keyspace. Calling truncate results in actual deletion of all data in the cluster under the given columnFamily and it will fail unless all hosts are up. All data in the given column family will be deleted, but its definition will not be affected.

Specified by:

truncate in interface StorageServiceMBean

Parameters:

keyspace - The keyspace to delete from

columnFamily - The column family to delete data from.

Throws:

java.util.concurrent.TimeoutException

getOwnership

public java.util.Map<java.net.InetAddress,java.lang.Float> getOwnership()

effectiveOwnership

public java.util.LinkedHashMap<java.net.InetAddress,java.lang.Float> effectiveOwnership(java.lang.String keyspace)

Calculates ownership. If there are multiple DC's and the replication strategy is DC aware then ownership will be calculated per dc, i.e. each DC will have total ring ownership divided amongst its nodes. Without replication total ownership will be a multiple of the number of DC's and this value will then go up within each DC depending on the number of replicas within itself. For DC unaware replication strategies, ownership without replication will be 100%.

Specified by:

effectiveOwnership in interface StorageServiceMBean

Throws:

java.lang.IllegalStateException - when node is not configured properly.
