protected void releaseLock(MasterProcedureEnv env)

Overrides:

releaseLock in class AbstractStateMachineTableProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState>

executeFromState

protected StateMachineProcedure.Flow executeFromState(MasterProcedureEnv env,
                                                      org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState state)
                                               throws ProcedureSuspendedException,
                                                      ProcedureYieldException,
                                                      InterruptedException

Specified by:

executeFromState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState>

Throws:

ProcedureSuspendedException

ProcedureYieldException

InterruptedException

preflightChecks

protected void preflightChecks(MasterProcedureEnv env,
                               Boolean enabled)
                        throws HBaseIOException

Description copied from class: AbstractStateMachineTableProcedure

Check that cluster is up and master is running. Check table is modifiable. If enabled, check table is enabled else check it is disabled. Call in Procedure constructor so can pass any exception to caller.

Overrides:

preflightChecks in class AbstractStateMachineTableProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState>

enabled - If true, check table is enabled and throw exception if not. If false, do the inverse. If null, do no table checks.

Throws:

HBaseIOException

rollbackState

protected void rollbackState(MasterProcedureEnv env,
                             org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState state)
                      throws IOException,
                             InterruptedException

Specified by:

rollbackState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState>

Throws:

IOException

InterruptedException

Description copied from interface: TableProcedureInterface

Returns the name of the table the procedure is operating on

Specified by:

getTableName in interface TableProcedureInterface

Specified by:

getTableName in class AbstractStateMachineTableProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState>

getTableOperationType

public TableProcedureInterface.TableOperationType getTableOperationType()

Description copied from interface: TableProcedureInterface

Given an operation type we can take decisions about what to do with pending operations. e.g. if we get a delete and we have some table operation pending (e.g. add column) we can abort those operations.

Specified by:

getTableOperationType in interface TableProcedureInterface

Specified by:

getTableOperationType in class AbstractStateMachineTableProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState>

Returns:

the operation type that the procedure is executing.
