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 AbstractStateMachineRegionProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.TruncateRegionState>

Returns:

the operation type that the procedure is executing.
