public TableBackupFuture(HBaseAdmin admin,
                         TableName tableName,
                         MasterProtos.BackupTablesResponse response)

Method Detail

getOperationType

public java.lang.String getOperationType()

Specified by:

getOperationType in class HBaseAdmin.TableFuture<java.lang.String>

Returns:

the operation type like CREATE, DELETE, DISABLE etc.

convertResult

protected java.lang.String convertResult(MasterProtos.GetProcedureResultResponse response)
                                  throws java.io.IOException

Description copied from class: HBaseAdmin.ProcedureFuture

Convert the procedure result response to a specified type.

Overrides:

convertResult in class HBaseAdmin.ProcedureFuture<java.lang.String>

Parameters:

response - the procedure result object to parse

Returns:

the result data of the procedure.

Throws:

java.io.IOException

postOperationResult

protected java.lang.String postOperationResult(java.lang.String result,
                                               long deadlineTs)
                                        throws java.io.IOException,
