Hi all, I've configured a Zookeeper cluster of 3 servers. The configuration of each one of the servers follows ~~~~~~~~ Server myid=1 PID:16543~~~~~~~~~~~~~ dataDir=/opt/zookeeper-3.4.6/zookeeper-data/1 clientPort=6815 server.1=mymachine:6816:6817 server.2=mymachine:6818:6819 server.3=mymachine:6820:6821
~~~~~~~~ Server myid=2 PID:16815~~~~~~~~~~~~~ dataDir=/opt/zookeeper-3.4.6/zookeeper-data/2 clientPort=6825 server.1=mymachine:6816:6817 server.2=mymachine:6818:6819 server.3=mymachine:6820:6821 ~~~~~~~~ Server myid=3 PID:16866~~~~~~~~~~~~~ dataDir=/opt/zookeeper-3.4.6/zookeeper-data/2 clientPort=6835 server.1=mymachine:6816:6817 server.2=mymachine:6818:6819 server.3=mymachine:6820:6821 I expect the above configuration - once the quorum is up and functional - to make use only of the ports defined (6815,6825,6835, 6816,6817,6818,6819,6820,6821) Calling a "netstat -nap" on all 3 of the above processes I get the following results. ~~~~~~~~~~~~ netstat for zk process with myid=1 ~~~~~~~~~~~~~~~ tcp6 0 0 :::6815 :::* LISTEN 16543/java tcp6 0 0 127.0.1.1:6816 :::* LISTEN 16543/java tcp6 0 0 127.0.1.1:6817 :::* LISTEN 16543/java tcp6 0 0 :::34657 :::* LISTEN 16543/java tcp6 0 0 127.0.1.1:6817 127.0.0.1:50770 ESTABLISHED 16543/java tcp6 0 0 127.0.1.1:6817 127.0.0.1:50766 ESTABLISHED 16543/java tcp6 0 0 127.0.1.1:6816 127.0.0.1:60441 ESTABLISHED 16543/java tcp6 0 0 127.0.1.1:6816 127.0.0.1:60437 ESTABLISHED 16543/java ~~~~~~~~~~~~ netstat for zk process with myid=2 ~~~~~~~~~~~~~~~ tcp6 0 0 127.0.1.1:6821 :::* LISTEN 16815/java tcp6 0 0 :::6835 :::* LISTEN 16815/java tcp6 0 0 :::47926 :::* LISTEN 16815/java tcp6 0 0 127.0.0.1:60437 127.0.1.1:6816 ESTABLISHED 16815/java tcp6 0 0 127.0.0.1:55381 127.0.1.1:6819 ESTABLISHED 16815/java tcp6 0 0 127.0.0.1:50766 127.0.1.1:6817 ESTABLISHED 16815/java ~~~~~~~~~~~~ netstat for zk process with myid=3 ~~~~~~~~~~~~~~~ tcp6 0 0 127.0.1.1:6819 :::* LISTEN 16866/java tcp6 0 0 :::6825 :::* LISTEN 16866/java tcp6 0 0 :::46305 :::* LISTEN 16866/java tcp6 0 0 127.0.1.1:6819 127.0.0.1:55381 ESTABLISHED 16866/java tcp6 0 0 127.0.0.1:60441 127.0.1.1:6816 ESTABLISHED 16866/java tcp6 0 0 127.0.0.1:50770 127.0.1.1:6817 ESTABLISHED 16866/java I see a lot of "randomly chosen" ports opened. I'd expect all communications to be established between the ports defined in the configuration. Am I doing something wrong? Due to these "random ports" I get port conficts with other services running on the same machine. I'm using zookeeper 3.4.6 and java 1.7.0_60 -- View this message in context: http://zookeeper-user.578899.n2.nabble.com/Zookeeper-listening-to-ports-other-than-clientPort-and-server-x-ports-tp7580137.html Sent from the zookeeper-user mailing list archive at Nabble.com.
