Aleksey Yeschenko updated CASSANDRA-11725: ------------------------------------------ Labels: lhf (was: ) > Check for unnecessary JMX port setting in env vars at startup > ------------------------------------------------------------- > > Key: CASSANDRA-11725 > URL: https://issues.apache.org/jira/browse/CASSANDRA-11725 > Project: Cassandra > Issue Type: Improvement > Components: Lifecycle > Reporter: Sam Tunnicliffe > Priority: Minor > Labels: lhf > Fix For: 3.x > > > Since CASSANDRA-10091, C* expects to always be in control of initializing its > JMX connector server. However, if {{com.sun.management.jmxremote.port}} is > set when the JVM is started, the bootstrap agent takes over and sets up the > server before any C* code runs. Because C* is then unable to bind the server > it creates to the specified port, startup is halted and the root cause is > somewhat unclear. > We should add a check at startup so a more informative message can be > provided. This would test for the presence of the system property which would > differentiate from the case where some other process is already bound to the > port. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
