rollback
Description copied from class:Procedure
The code to undo what was done by the execute() code. It is called when the procedure or one of the sub-procedures failed or an abort was requested. It should cleanup all the resources created by the execute() call. The implementation must be idempotent since rollback() may be called multiple time in case of machine failure in the middle of the execution.- Specified by:
rollback
in classProcedure<MasterProcedureEnv>
- Parameters:
env
- the environment passed to the ProcedureExecutor- Throws:
IOException
- temporary failure, the rollback will retry laterInterruptedException
- the procedure will be added back to the queue and retried later
-
abort
Description copied from class:Procedure
The abort() call is asynchronous and each procedure must decide how to deal with it, if they want to be abortable. The simplest implementation is to have an AtomicBoolean set in the abort() method and then the execute() will check if the abort flag is set or not. abort() may be called multiple times from the client, so the implementation must be idempotent.NOTE: abort() is not like Thread.interrupt(). It is just a notification that allows the procedure implementor abort.
- Specified by:
abort
in classProcedure<MasterProcedureEnv>
-
serializeStateData
Description copied from class:Procedure
The user-level code of the procedure may have some state to persist (e.g. input arguments or current position in the processing state) to be able to resume on failure.- Specified by:
serializeStateData
in classProcedure<MasterProcedureEnv>
- Parameters:
serializer
- stores the serializable state- Throws:
IOException
-
deserializeStateData
Description copied from class:Procedure
Called on store load to allow the user to decode the previously serialized state.- Specified by:
deserializeStateData
in classProcedure<MasterProcedureEnv>
- Parameters:
serializer
- contains the serialized state- Throws:
IOException
-
remoteCallBuild
public Optional<RemoteProcedureDispatcher.RemoteOperation> remoteCallBuild(MasterProcedureEnv masterProcedureEnv, ServerName remote) Description copied from interface:RemoteProcedureDispatcher.RemoteProcedure
For building the remote operation. May be empty if no need to send remote call. Usually, this means the RemoteProcedure has been finished already. This is possible, as we may have already sent the procedure to RS but then the rpc connection is broken so the executeProcedures call fails, but the RS does receive the procedure and execute it and then report back, before we retry again.- Specified by:
remoteCallBuild
in interfaceRemoteProcedureDispatcher.RemoteProcedure<MasterProcedureEnv,
ServerName>
-
getServerName
Description copied from interface:ServerProcedureInterface
Returns Name of this server instance.- Specified by:
getServerName
in interfaceServerProcedureInterface
-
hasMetaTableRegion
Description copied from interface:ServerProcedureInterface
Returns True if this server has an hbase:meta table region.- Specified by:
hasMetaTableRegion
in interfaceServerProcedureInterface
-
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 interfaceServerProcedureInterface
- Returns:
- the operation type that the procedure is executing.
-
complete
- Specified by:
complete
in classServerRemoteProcedure
-
toStringClassDetails
Description copied from class:Procedure
Extend the toString() information with the procedure details e.g. className and parameters- Overrides:

in classProcedure<MasterProcedureEnv>
- Parameters:
sb
- the string builder to use to append the proc specific information
