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.
