Xmn i= s the size of the heap for the young generation. If somebody new to Java just reads the Ambari description and set both Xmn = and Xmx to the same value, HBase will start but it will perform miserably. = Please fix the documentation for the two settings in Ambari GUI that refer = to Xmx (the ratio and the static value) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
