ClaimReplicationQueuesProcedure

public ClaimReplicationQueuesProcedure(ServerName crashedServer)

Method Detail

getServerName

public ServerName getServerName()

Description copied from interface: ServerProcedureInterface

Returns Name of this server instance.

Specified by:

getServerName in interface ServerProcedureInterface

hasMetaTableRegion

public boolean hasMetaTableRegion()

Description copied from interface: ServerProcedureInterface

Returns True if this server has an hbase:meta table region.

Specified by:

hasMetaTableRegion in interface ServerProcedureInterface

getServerOperationType

public ServerProcedureInterface.ServerOperationType getServerOperationType()

Description copied from interface: ServerProcedureInterface

Given an operation type we can take decisions about what to do with pending operations. e.g. if we get a crash handler and we have some assignment operation pending we can abort those operations.

Specified by:

getServerOperationType in interface ServerProcedureInterface

Returns:

the operation type that the procedure is executing.
