I think it's not that hurt.
In current change, new client is compatible with the old and new shuffle
service. In our clusters, we always upgrade the client first and then server
side, which will not cause incompatible issue. The only risk here is that user
upgrades the server but still using the old client. But I find no reason they
do this. I think users usually tend to upgrade the client first and then deploy
new servers gradually.
In our cluster, there are nodemanagers failing everyday because of OOM of
shuffle service. The root cause is that shuffle service is a hot point and
there is no concurrency control.
