Hi, I have come across the exact same issue a while ago. I am no expert but it seems balancer is not reassigning newly split regions, in order to reduce client disconnect problems, selecting other regions on the RS instead. I have seen a JIRA about this behaviour but i can't remember the id. Anyways, this is not a real solution but i overcame it by disabling unused tables. Still, i too am curious about some expert opinion.
