HBase init scripts are shut down in the wrong order

HBase init scripts, like all Hadoop init scripts, are killed at the same time (K20-*) in /etc/rc0.d and /etc/rc6.d.

If the HMaster and/or the datanode shuts down before the regionserver, this causes the regionserver to take a long time to actually give up and shut down, effectively blocking system shutdown. This is a big problem on my pseudo-distributed instance on my laptop.

The init script default stops for HBase services should be set to something like:

• K17hadoop-hbase-regionserver
• K18hadoop-hbase-master
• K19hadoop-zookeeper-server
• K20hadoop-*
