构造器详细资料

TableFuture

public TableFuture(HBaseAdmin admin,
                   TableName tableName,
                   Long procId)

方法详细资料

toString

public String toString()

覆盖:

toString 在类中 Object

getTableName

protected TableName getTableName()

返回:

the table name

getTableDescriptor

protected TableDescriptor getTableDescriptor()
                                      throws IOException

返回:

the table descriptor

抛出:

IOException

getOperationType

public abstract String getOperationType()

返回:

the operation type like CREATE, DELETE, DISABLE etc.

getDescription

protected String getDescription()

返回:

a description of the operation

postOperationResult

protected V postOperationResult(V result,
                                long deadlineTs)
                         throws IOException,
                                TimeoutException

从类复制的说明: HBaseAdmin.ProcedureFuture

Called after the operation is completed and the result fetched. this allows to perform extra steps after the procedure is completed. it allows to apply transformations to the result that will be returned by get().

覆盖:

postOperationResult 在类中 HBaseAdmin.ProcedureFuture<V>

参数:

result - the result of the procedure

deadlineTs - the timestamp after which this method should throw a TimeoutException

返回:

the result of the procedure, which may be the same as the passed one

抛出:

IOException

TimeoutException

postOperationFailure

protected V postOperationFailure(IOException exception,
                                 long deadlineTs)
                          throws IOException,
                                 TimeoutException

从类复制的说明: HBaseAdmin.ProcedureFuture

Called after the operation is terminated with a failure. this allows to perform extra steps after the procedure is terminated. it allows to apply transformations to the result that will be returned by get(). The default implementation will rethrow the exception

覆盖:

postOperationFailure 在类中 HBaseAdmin.ProcedureFuture<V>

参数:

exception - the exception got from fetching the result

deadlineTs - the timestamp after which this method should throw a TimeoutException

返回:

the result of the procedure, which may be the same as the passed one

抛出:

IOException

TimeoutException

waitForTableEnabled

protected void waitForTableEnabled(long deadlineTs)
                            throws IOException,
                                   TimeoutException

抛出:

IOException

TimeoutException

waitForTableDisabled

protected void waitForTableDisabled(long deadlineTs)
                             throws IOException,
                                    TimeoutException

抛出:

IOException

TimeoutException

waitTableNotFound

protected void waitTableNotFound(long deadlineTs)
                          throws IOException,
                                 TimeoutException

抛出:

waitForAllRegionsOnline

protected void waitForAllRegionsOnline(long deadlineTs,
                                       byte[][] splitKeys)
                                throws IOException,
                                       TimeoutException
