replicateWALEntry

public static void replicateWALEntry(AdminProtos.AdminService.BlockingInterface admin,
                                     WAL.Entry[] entries,
                                     java.lang.String replicationClusterId,
                                     Path sourceBaseNamespaceDir,
                                     Path sourceHFileArchiveDir)
                              throws java.io.IOException

A helper to replicate a list of WAL entries using admin protocol.

Parameters:

admin - Admin service

entries - Array of WAL entries to be replicated

replicationClusterId - Id which will uniquely identify source cluster FS client configurations in the replication configuration directory

sourceBaseNamespaceDir - Path to source cluster base namespace directory

sourceHFileArchiveDir - Path to the source cluster hfile archive directory

Throws:

java.io.IOException

buildReplicateWALEntryRequest

public static Pair<AdminProtos.ReplicateWALEntryRequest,CellScanner> buildReplicateWALEntryRequest(WAL.Entry[] entries)

Create a new ReplicateWALEntryRequest from a list of WAL entries

Parameters:

entries - the WAL entries to be replicated

Returns:

a pair of ReplicateWALEntryRequest and a CellScanner over all the WALEdit values found.

buildReplicateWALEntryRequest

public static Pair<AdminProtos.ReplicateWALEntryRequest,CellScanner> buildReplicateWALEntryRequest(WAL.Entry[] entries,
                                                                                                   byte[] encodedRegionName,
                                                                                                   java.lang.String replicationClusterId,
                                                                                                   Path sourceBaseNamespaceDir,
                                                                                                   Path sourceHFileArchiveDir)

Create a new ReplicateWALEntryRequest from a list of HLog entries

Parameters:

entries - the HLog entries to be replicated

encodedRegionName - alternative region name to use if not null

replicationClusterId - Id which will uniquely identify source cluster FS client configurations in the replication configuration directory

sourceBaseNamespaceDir - Path to source cluster base namespace directory

sourceHFileArchiveDir - Path to the source cluster hfile archive directory

Returns:

a pair of ReplicateWALEntryRequest and a CellScanner over all the WALEdit values found.
