Subject [jira] [Created] (BIGTOP-239) HBase init scripts are shut down in the wrong order

HBase init scripts are shut down in the wrong order
---------------------------------------------------

                 Key: BIGTOP-239
                 URL: https://issues.apache.org/jira/browse/BIGTOP-239
             Project: Bigtop
          Issue Type: Sub-task
          Components: General
    Affects Versions: 0.1.0
            Reporter: Peter Linnell
            Assignee: Peter Linnell
            Priority: Critical
             Fix For: 0.3.0


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-*
