Description

I noticed that when testing for PHOENIX-5112.

Looks like each time we split during a scan we'll get an exception to the client.

With the problems mentioned in PHOENIX-4849 in mind, I think this is expected, but I wanted to track this here. Specifically there are other scenarios (such as aggregates) where restart upon split cannot be supported.
