所有已实现的接口:

Comparable<Procedure<MasterProcedureEnv>>, MetaProcedureInterface

已过时。

Do not use any more, leave it here only for compatible. The recovery work will be done in ServerCrashProcedure directly, and the initial work for meta table will be done by InitMetaProcedure.

@Deprecated
 @InterfaceAudience.Private
public class RecoverMetaProcedure
extends StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.RecoverMetaState>
implements MetaProcedureInterface

This procedure recovers meta from prior shutdown/ crash of a server, and brings meta online by assigning meta region/s. Any place where meta is accessed and requires meta to be online, need to submit this procedure instead of duplicating steps to recover meta in the code.

RecoverMetaProcedure

public RecoverMetaProcedure(ServerName failedMetaServer,
                            boolean shouldSplitLog)

已过时。

Call this constructor to queue up a RecoverMetaProcedure in response to meta carrying server crash

参数:

failedMetaServer - failed/ crashed region server that was carrying meta

shouldSplitLog - split log file of meta region

RecoverMetaProcedure

public RecoverMetaProcedure(ServerName failedMetaServer,
                            boolean shouldSplitLog,

已过时。

Constructor with latch, for blocking/ sync usage

RecoverMetaProcedure

public RecoverMetaProcedure()

已过时。

This constructor is also used when deserializing from a procedure store; we'll construct one of these then call #deserializeStateData(InputStream). Do not use directly.
