Nick Dimiduk commented on HBASE-15523:
--------------------------------------

This sounds like the realm of system management tools -- write an init or upstart or whatever script for it, right? I have one in https://github.com/ndimiduk/cesnet-hbase/blob/hdp/templates/services/hbase-regionserver.conf.erb

Maybe whatever tools builds the RPM should also include system service scripts for its target platform. See also http://mail-archives.apache.org/mod_mbox/hbase-dev/201606.mbox/%3CCANZa=GsMsAz0R=BKzGO7ThZNHbh=HS5L=evofnB-A7_3BDsYqA@mail.gmail.com%3E
