Alternatively RPC or NN can > throw some well defined exception back to the client based on certain > policies when it is under heavy load; client will understand such exception > and do exponential back off, as another implementation of > RetryInvocationHandler. -- This message was sent by Atlassian JIRA (v6.2#6252)
