Subject Question About Starting and Stopping HADOOP & HBASE Cluster in Secure Mode
Date Tue, 27 Nov 2012 11:28:00 GMT

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

   stop the cluster from Master:
   (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
