Method Detail

init

public void init(ReplicationEndpoint.Context context)
          throws IOException

Description copied from interface: ReplicationEndpoint

Initialize the replication endpoint with the given context.

Specified by:

init in interface ReplicationEndpoint

Overrides:

init in class BaseReplicationEndpoint

Parameters:

context - replication context

Throws:

IOException

doStart

protected void doStart()

Overrides:

doStart in class HBaseReplicationEndpoint

doStop

protected void doStop()

Overrides:

doStop in class HBaseReplicationEndpoint

getDefaultThreadPool

private ExecutorService getDefaultThreadPool(org.apache.hadoop.conf.Configuration conf)

Returns a Thread pool for the RPC's to region replicas. Similar to Connection's thread pool.

replicate

public boolean replicate(ReplicationEndpoint.ReplicateContext replicateContext)

Description copied from interface: ReplicationEndpoint

Replicate the given set of entries (in the context) to the other cluster. Can block until all the given entries are replicated. Upon this method is returned, all entries that were passed in the context are assumed to be persisted in the target cluster.

Parameters:

replicateContext - a context where WAL entries and other parameters can be obtained.

canReplicateToSameCluster

public boolean canReplicateToSameCluster()

Description copied from interface: ReplicationEndpoint

Whether or not, the replication endpoint can replicate to it's source cluster with the same UUID

Specified by:

canReplicateToSameCluster in interface ReplicationEndpoint

Overrides:

canReplicateToSameCluster in class BaseReplicationEndpoint

getScopeWALEntryFilter

protected WALEntryFilter getScopeWALEntryFilter()

Description copied from class: BaseReplicationEndpoint

Returns a WALEntryFilter for checking the scope. Subclasses can return null if they don't want this filter

Overrides:

getScopeWALEntryFilter in class BaseReplicationEndpoint
