[jira] [Commented] (HBASE-28088) NullPointerException authorizing connection on regionserver startup
[ https://issues.apache.org/jira/browse/HBASE-28088?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17765852#comment-17765852 ]

-------------------------------------------
The above described call path is based on branch-2. The call path is different on master, but I think the same problem exists there.

> When a RegionServer starts up, the HRegionServer constructor calls createRpcServices() which creates RSRpcServices, which uses RpcServerFactory to create a NettyRpcServer. The NettyRpcServer constructor binds the process to the given regionserver port. At this point it is able to accept requests.
> Later in the HRegionServer constructor, it calls rpcServices.start(zooKeeper). This calls NettyRpcServer.start(), which initializes the AuthManager.
> Since there is a period of time where the server can accept requests but AuthManager is not initialized, if you have authentication enabled you will receive NullPointerExceptions (see below). These will clear up once the server starts.
> We should fix the flow here to avoid these errors.
