zookeeper 3.4.6 listening on unknown random port
Hi All,
Im running a 3 zookeeper process and noticed all 3 zookeeper process is
listening on one unknown random port.
Can someone please help me to understand why is this port used for ?
This port not handling any connections and all the 3 zookeeper has
different port number.
Node1 -> has 1 zookeeper (z1)
node2 -> has 2 zookeeper (z3 & z3)
server.1=z1.zookeeper.com:2888:3888
server.2=z2.zookeeper.com:2888:3888
server.3=z3.zookeeper.com:2889:3889

Here "z1,z2,z3" are listening on "36895, 40037 & 42455" port respectively
which has not been configured.
Thanks.

Hi Rakesh,
No, I haven't configured any JMX port for zookeeper.
may be it's jmx remote monitoring port.
Thank you.

Mazhar Shaikh.

Hi Mazhar,
I doubt the possibility of jmx remote monitoring random port. Did you
configure environment variable JMXPORT to avoid random port ?
