ls: java.io.IOException: java.net.ConnectException: Connection refused

On host abbey-road I have 2 docker containers, one each for namenode and
datanode.  I can successfully use -ls from same VM:

[root@abbey-road ~]# /usr/local/apache-crail-1.2-incubating/bin/crail fs
-ls /
Found 1 items
-rw-rw-rw-   1 crail crail         11 2020-02-21 14:39 /HelloWorld

I try the same from VM ringo-starr and get the subject Exception.

[root@ringo-starr ~]# cd $CRAIL_HOME
[root@ringo-starr apache-crail-1.2-incubating]# grep abbey-road conf/*
conf/core-site.xml:    <value>crail://abbey-road:9060</value>
conf/crail-site.conf:crail.namenode.address
 crail://abbey-road:9060
