> As part of HBASE-5939, the autorestart for hbase services has been added to
> deal with scenarios where hbase services (master/regionserver/master-backup)
> gets killed or goes down leading to unplanned outages. The changes were made
> to hbase-daemon.sh to support autorestart option.
> However, the autorestart implementation doesn't work in standalone mode and
> other than that have few gaps with the implementation as per release notes of
> HBASE-5939. Here is an attempt to re-design and fix the functionality
> considering all possible usecases with hbase service operations.
> Release Notes of HBASE-5939:
> ------------------------------------------
> When launched with autorestart, HBase processes will automatically restart if
> they are not properly terminated, either by a "stop" command or by a cluster
> stop. To ensure that it does not overload the system when the server itself
> is corrupted and the process cannot be restarted, the server sleeps for 5
> minutes before restarting if it was already started 5 minutes ago previously.
> To use it, launch the process with "bin/start-hbase autorestart". This option
> is not fully compatible with the existing "restart" command: if you ask for a
> restart on a server launched with autorestart, the server will restart but
> the next server instance won't be automatically restarted.
