Configure and Start Apache Accumulo

Before you can upgrade Apache Accumulo, you must have first upgraded your HDP components to the latest version (in this case, 2.4.2). This section assumes that you have already upgraded your components for HDP 2.4.2. If you have not already completed these steps, return to Getting Ready to Upgrade and Upgrade 2.3 Components for instructions on how to upgrade your HDP components to 2.4.2.

	Note
	The `su` commands in this section use "accumulo" to represent the Accumulo Service user. If you are using another name for your Accumulo Service user, you will need to substitute your Accumulo Service user name for "accumulo" in each of the `su` commands.

You must replace your configuration after upgrading. Copy /etc/accumulo/conf from the template to the conf directory in Accumulo hosts.

Start the services:

su - accumulo -c "/usr/hdp/current/accumulo-master/bin/start-server.sh `hostname` master"
                
su - accumulo -c "/usr/hdp/current/accumulo-master/bin/start-server.sh `hostname` tserver"

su - accumulo -c "/usr/hdp/current/accumulo-master/bin/start-server.sh `hostname` gc"

su - accumulo -c "/usr/hdp/current/accumulo-master/bin/start-server.sh `hostname` tracer"

su - accumulo -c "/usr/hdp/current/accumulo-master/bin/start-server.sh `hostname` monitor"

Check that the processes are running
ps -ef | grep accumulo
or visit http://<hostname>:50095 in your browser
