Question About Starting and Stopping HADOOP & HBASE Cluster in Secure Mode

Tue, 27 Nov 2012 07:58:56 -0800 

Hi,

I currently use the following steps to start and stop HADOOP & HBASE cluster:

1) Without Kerberos Security
   (start zookeepers)
   start the cluster from Master:
      {$HADOOP_HOME}/bin/start-dfs.sh                           // one command 
start all servers
      {$HADOOP_HOME}/bin/start-mapred.sh                
      {$HBASE_HOME}/bin/start-hbase.sh 

   stop the cluster from Master:
      {$HBASE_HOME}/bin/stop-hbase.sh 
      {$HADOOP_HOME}/bin/stop-mapred.sh
      {$HADOOP_HOME}/bin/stop-dfs.sh
   (stop zookeepers)


2) With Kerberos and in Secure Mode
   start the HADOOP Namenode 
      {$HADOOP_HOME}/bin/hadoop-daemon.sh start namenode 
       then for each datanode:
      {$HADOOP_HOME}/bin/hadoop-daemon.sh start datanode  
   then HBASE Master: 
      {$HBASE_HOME}/bin/hbase-daemon.sh start master (as root)
       then for each HBASE regionserver:
      {$HBASE_HOME}/bin/hbase-daemon.sh start regionserver 


QUESTION: As I can see from 2) there are more steps to start the entire cluster 
in secure node, are there any existing commands which simplify start/stop 
HADOOP & HBASE in Secure mode? 

Thanks
ac
