Kirk Lund reassigned GEODE-6285: -------------------------------- Assignee: Kirk Lund > MBean names in Loner are not stable when member name is empty > ------------------------------------------------------------- > > Key: GEODE-6285 > URL: https://issues.apache.org/jira/browse/GEODE-6285 > Project: Geode > Issue Type: Bug > Components: jmx > Reporter: Kirk Lund > Assignee: Kirk Lund > Priority: Major > > When the default member name is empty, Geode uses DistributedMember.getId() > instead of DistributedMember.getName() in the MBean names. If the member is a > Loner (no cluster) then it will mutate the string returned from > DistributedMember.getId() at runtime if a CacheServer or GatewayReceiver is > created and started. > Example: > When GatewayReceiver is created, Geode creates a GatewayReceiverMXBean with > the ObjectName > *GemFire:service=CacheServer,port=\{0\},type=Member,member=\{1\}*. The > *\{1\}* parameter value is *10.118.20.84(28927-loner)-0-6ea32c5* which > contains a zero where the membership port would normally be displayed: > {noformat} > GemFire:service=GatewayReceiver,type=Member,member=10.118.20.84(28927-loner)-0-6ea32c59 > {noformat} > Then when the GatewayReceiver is started, Geode fails to update the > GatewayReceiverMXBean state to reflect that it's running because the simple > act of starting the GatewayReceiver resulted in the changing of > DistributedMember.getId() to replace the membership port of zero with the > port that the GatewayReceiver is now listening on: > {noformat} > GemFire:service=GatewayReceiver,type=Member,member=10.118.20.84(28927-loner)-5362-6ea32c59 > {noformat} > Internally the code tries to find an existing GatewayReceiverMXBean with that > ObjectName and returns null. The code after that doesn't expect the MBean to > be null, so updating it fails. Later if the GatewayReceiver is destroyed, it > also fails to unregister the MBean as well. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
