nkeywal commented on HBASE-5844:
--------------------------------

Patch v1. Tested on a local cluster & pseudo distributed, by stopping the server by kill -9. I will do some minor improvements on the java code and then test on a real cluster, but I'm interested by a feedback on the script.

> today, if the regions server crashes, its znode is not deleted in ZooKeeper. So the recovery process will stop only after a timeout, usually 30s.
> By deleting the znode in start script, we remove this delay and the recovery starts immediately.
