Josh Elser commented on ACCUMULO-4728:
--------------------------------------

bq. An otherwise well functioning tserver may fail to load a tablet indefinitely

Can you provide some context about how you've seen this in practice? Understanding why we're stuck indefinitely here would help significantly in picking the best solution.

> An otherwise well functioning tserver may fail to load a tablet indefinitely without the master re-assigning the tablet to another tserver. In some cases the tserver may be miss configured in some way that prevents loading a set of specific tablets from a specific set of tables. 
> If the tserver could respond to the master with a failure to load a tablet and abort the master could then re-assign the tablet somewhere else. In some instances this could prevent an outage.
