[jira] [Commented] (HADOOP-7392) Implement capability of querying
individual property of a mbean using JMXProxyServlet
[ https://issues.apache.org/jira/browse/HADOOP-7392?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13052157#comment-13052157 ]
Luke Lu commented on HADOOP-7392:
---------------------------------
# I think /jmx should preserve the current behavior: list all mbeans, when no parameters are specified.
# Need to document the get syntax in the javadoc.
# Need to handle cases when property does(n't exist and make sure propertyinfo doesn't cause NPE later.
# Need to set the response status to 404 (SC_NOT_FOUND) if the property is not found.
