Method Detail

prepare

public void prepare(boolean reload)
             throws IOException

Description copied from interface: RetryingCallable

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

Specified by:

prepare in interface RetryingCallable<org.apache.hadoop.hbase.shaded.protobuf.generated.AdminProtos.FlushRegionResponse>

Overrides:

prepare in class RegionAdminServiceCallable<org.apache.hadoop.hbase.shaded.protobuf.generated.AdminProtos.FlushRegionResponse>

Parameters:

reload - Set this to true if need to requery locations

Throws:

IOException - e

call

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

Description copied from class: RegionAdminServiceCallable

Run RPC call.

Specified by:

call in class RegionAdminServiceCallable<org.apache.hadoop.hbase.shaded.protobuf.generated.AdminProtos.FlushRegionResponse>

Parameters:

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. n

Throws:

Exception
