Jian Zhang updated HDFS-17544:
------------------------------
Description:
*Describe*
In order not to affect other modules, when implementing router asynchronous
client rpc protocolPB, it mainly extends the original protocolPB; The
implemented protocolPB is as follows:
*RouterClientProtocolTranslatorPB* extends ClientNamenodeProtocolTranslatorPB
*RouterGetUserMappingsProtocolTranslatorPB* extends
GetUserMappingsProtocolClientSideTranslatorPB
*RouterNamenodeProtocolTranslatorPB* extends NamenodeProtocolTranslatorPB
*RouterRefreshUserMappingsProtocolTranslatorPB* extends
RefreshUserMappingsProtocolClientSideTranslatorPB
Then let the router's *ConnectionPool* use the aforementioned protocolPB
In the implementation of asynchronous Rpc.client, the main methods used include
HADOOP-13226, HDFS-10224, etc
{*}AsyncRpcProtocolPBUtil{*}: Make the implementation of asynchronous rpc
protocol more concise and clear.
*Test*
I modified RouterRpcClient to use asynchronous client protocolPB for testing.
{*}Note{*}: For a discussion on the AsyncUtil introduced by this PR, please
refer to it HDFS-17543 This PR requires the use of this tool; Please ignore
the modification of RouterRpcClient, just for the convenience of testing the
asynchronous client mentioned above.
