Apache HBaseは列指向の分散データベースです。
〇Ambariの画面
ブラウザでhttp://192.168.1.117:8080/にアクセスします。ユーザ/パスワードはadmin/adminです。
〇構築方法
以下のVagrantfileを使用して、Ambari/HDFS/HBaseをインストールした仮想マシン(CentOS7.4)を構築する事ができます。
Vagrantfile

vbox.name = "co74hbase.vm.internal"
vbox.cpus = 4
vbox.memory = 10240
vbox.customize ["modifyvm", :id, "--nicpromisc2","allow-all"]
