方法详细资料

prepare

public void prepare(boolean reload)
             throws IOException

从接口复制的说明: RetryingCallable

Prepare by setting up any connections to servers, etc., ahead of call invocation. TODO: We call prepare before EVERY call. Seems wrong. FIX!!!!

指定者:

prepare 在接口中 RetryingCallable<org.apache.hadoop.hbase.shaded.protobuf.generated.AdminProtos.FlushRegionResponse>

覆盖:

prepare 在类中 RegionAdminServiceCallable<org.apache.hadoop.hbase.shaded.protobuf.generated.AdminProtos.FlushRegionResponse>

参数:

reload - Set this to true if need to requery locations

抛出:

IOException - e

call

protected org.apache.hadoop.hbase.shaded.protobuf.generated.AdminProtos.FlushRegionResponse call(HBaseRpcController controller)
                                                                                          throws Exception

从类复制的说明: RegionAdminServiceCallable

Run RPC call.

指定者:

call 在类中 RegionAdminServiceCallable<org.apache.hadoop.hbase.shaded.protobuf.generated.AdminProtos.FlushRegionResponse>

参数:

controller - PayloadCarryingRpcController is a mouthful but it at a minimum is a facade on protobuf so we don't have to put protobuf everywhere; we can keep it behind this class.

抛出:

Exception
