[jira] [Created] (HADOOP-7931) o.a.h.ipc.WritableRpcEngine should
have a way to force initialization
o.a.h.ipc.WritableRpcEngine should have a way to force initialization
---------------------------------------------------------------------
Key: HADOOP-7931
URL: https://issues.apache.org/jira/browse/HADOOP-7931
Project: Hadoop Common
Issue Type: Bug
Components: ipc
Affects Versions: 0.24.0
Reporter: Aaron T. Myers
Assignee: Aaron T. Myers
{{WritableRpcEngine}} currently relies on a static initializer to register itself with {{o.a.h.ipc.Server}} as a valid {{RpcKind}}. There should be a way to ensure this initialization has already occurred.

-----------------------------------------
Aaron, why not just move the static initialization to ipc.Server. Then there is not need to make a call ensureInitialized() right?

----------------------------------------
bq. Aaron, why not just move the static initialization to ipc.Server. Then there is not need to make a call ensureInitialized() right?
Because presumably o.a.h.ipc.Server is supposed to be independent of underlying {{RpcEngine}} implementations, which is why there's a {{resgisterProtocolEngine}} method in the first place. If that's not in fact a design goal, then sure, adding the initialization to {{ipc.Server}} is fine.

-----------------------------------------
+1 for your patch. I plan to cleanup this later. The way RpcEngines are initialized is not correct currently. Will clean it up later.
