Description

An issue we faced recently on the YCSB cluster is that some disks got full and there was no easy way to bring the tservers back. We had a lot of old tables we could have deleted but in order to do that the tablets must first go through bootstrapping... which is impossible on a full disk.

Ideas (Todd's mostly):

• Add a configurable delay (default:0s) when a tserver starts before it bootstraps, this way it could get DeleteTablet calls from the master.
• Make it possible to delete tablets while they are in queue to bootstrap.
• Make it possible to delete bootstrapping tablets.
