> RPC server does not handle the AccessControlException thrown by
> authorizeConnection failure properly and in return sends IOException to the
> HBase client.
> Ultimately the client does retries and gets RetriesExhaustedException but
> does not getting any link or information or stack trace about
> AccessControlException.
> In short summary, upon inspection of RPCServer.java, it seems
> for the Listener, the Reader read code as below does not handle
> AccessControlException
> {noformat}
> void doRead(….
> …..
> …..
> try {
> count = c.readAndProcess(); // This readAndProcess method throws
> AccessControlException from processOneRpc(byte[] buf) which is not handled ?
> } catch (InterruptedException ieo) {
> throw ieo;
> } catch (Exception e) {
> LOG.warn(getName() + ": count of bytes read: " + count, e);
> count = -1; //so that the (count < 0) block is executed
> }
> {noformat}
> Below is the client logs if authorizeConnection throws AccessControlException:
