Run the following command to register Jubatus Yum repository to the system.

// For RHEL 6
$ sudo rpm -Uvh http://download.jubat.us/yum/rhel/6/stable/x86_64/jubatus-release-6-2.el6.x86_64.rpm

// For RHEL 7
$ sudo rpm -Uvh http://download.jubat.us/yum/rhel/7/stable/x86_64/jubatus-release-7-2.el7.x86_64.rpm

Then install jubatus and jubatus-client package.
