abort

public boolean abort(MasterProcedureEnv env)

指定者:

abort 在类中 Procedure<MasterProcedureEnv>

acquireLock

protected boolean acquireLock(MasterProcedureEnv env)

覆盖:

acquireLock 在类中 Procedure<MasterProcedureEnv>

从接口复制的说明: 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.

指定者:

getTableOperationType 在接口中 TableProcedureInterface

返回:

the operation type that the procedure is executing.
