Query on Solr and ZK ports
Hi All,
I could see the solr process is Listening on 7981 port along with the
normal solr port(8981). It is shown as DSTOP PORT , when I grep solr
process. Could you please give more details on this port, Can we disable
this ?
With regards to Zookeeper I could see port 8080 as a ZK admin port, How can
I use this, can i disable it if I don't want it ?
Also I could see ZK is listening on some random port (43801) along with the
other ports. Please throw some light on this.

Thanks and Regards,
Hari

ZK admin server port is 8080,
https://zookeeper.apache.org/doc/r3.5.1-alpha/zookeeperAdmin.html#sc_adminserver
In my usage in the past, it spits out useful metrics around number of times
a znode was accessed.

Hi,
See https://unix.stackexchange.com/questions/684348/solr-ports-in-use for an answer.
The STOP_PORT is the Jetty Servlet container's way to shutting down. It will only listen on localhost, so you need to use bin/solr stop command on the host, i.e. no need to expose this port to the outside.
Wrt ZK ports, Only port 2181 needs to be open between Solr and ZK, but between the Zookeepers, also ports 2888 and 3888 needs to be open for internal communication, see https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.6.0/bk_reference/content/zookeeper-ports.html I'm not aware of other ports.
