Throws:

InterruptedException

abort

protected boolean abort(MasterProcedureEnv env)

Overrides:

rollbackState

protected void rollbackState(MasterProcedureEnv env,
                             org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.DeleteTableState state)

Specified by:

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

isRollbackSupported

protected boolean isRollbackSupported(org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.DeleteTableState state)

Overrides:

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

getState

protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.DeleteTableState getState(int stateId)

getTableName

public TableName getTableName()

Specified by:

getTableName in interface TableProcedureInterface

Specified by:

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

Returns:

the name of the table the procedure is operating on

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.DeleteTableState>

Returns:

the operation type that the procedure is executing.
