----------------------------------

We cannot tell if the attempts are garbage beforehand. The server can become a
leader anytime. However, NotLeaderException handling with no sleep probably
is too aggressive.
> Garbage collection due to same request retries on a follower

>
> In a heap dump it could be seen that a client request retries on the same
> follower multiple times and every time the request is rejected with a
> NotLeaderException. In case of Ozone it is a WriteChunk request which leads
> to garbage collection of 16MB for every request. In the heap dump a client
> request retries multiple times leading to garbage collection of ~100MB.
