hadoop hbase /etc/init.d style startup scripts

I scoured the InterTubes for example hadoop/hbase startup scripts and found absolutely none! I ended up creating a minimal one that is so far only suited for the Pseudo-Distributed Operation mode as it just calls the start-all / stop-all scripts.

/etc/init.d/hadoop
Create the place it will put its startup logs

mkdir /var/log/hadoopCreate /etc/init.d/hadoop with the following:

#!/bin/sh

Set up the init system
This assumes you put the above init files in /etc/init.d

chmod +x /etc/init.d/{hbase,hadoop}
update-rc.d hadoop defaults
update-rc.d hbase defaults 25You can now start / stop hadoop by saying:

/etc/init.d/hadoop start/etc/init.d/hadoop stopAnd similarly with hbase

/etc/init.d/hbase start/etc/init.d/hbase stopMake sure you start hadoop before hbase and stop hbase before you stop hadoop
