-------------------------------------------
Summary: Ambari UI for HBase config incorrectly describes the -Xmn
config
Key: AMBARI-10350
URL: https://issues.apache.org/jira/browse/AMBARI-10350
Project: Ambari
Issue Type: Bug
Components: ambari-server
Reporter: Dmitry Lysnichenko
Assignee: Dmitry Lysnichenko
Fix For: 2.1.0
Ambari GUI for HBase config incorrectly describes the -Xmn as the “maximum
value for the minimum heap size”, which is incorrect. Xmn is 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)
