Switch to virtualbox/vmware console :

and logon to this console with username/password as root/hadoop (default)

on root prompt type

docker exec -i sandbox passwd and type the new password. as shown in this picture

Now go to browser and access the shell with new password

or do ssh root@localhost -p 2222 and keyin new password set in above screen.

you can use putty from windows machine and run any hdfs command.

I have tried this command in 2.6 version unsuccessfully but successfully with "sandbox-hdp" container.

docker exec -i sandbox-hdp passwd

After introducing password twice you have to finish with ^C.

Best regards
