Subject [jira] [Commented] (CASSANDRA-13578) mx4j configuration minor improvement
Date Thu, 08 Jun 2017 22:47:18 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13578?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16043563#comment-16043563
] 

Jay Zhuang commented on CASSANDRA-13578:
----------------------------------------

The problem is if anyone set {{MX4J_PORT=8081}} in the env instead of {{MX4J_PORT=-Dmx4jport=8081}},
Cassandra will fail to start:
{{noformat}}
$ ./bin/cassandra

{{noformat}}

So I think it worth to have this change in 4.0.
