It shares the same info server with the regionserver. We can have a setting so that we can start two info servers, one for the master on the original port, and one for the regionserver. > * Backup master is a regionserver now. So it could hold regions. This could affect some deployment. We can have a setting so that we can prevent backup master from serving any region. -- This message was sent by Atlassian JIRA (v6.2#6252)
