Docker Sandbox HDP 2.5 - Error 255

Hi,

I am trying to run Docker Sandbox HDP 2.5 image in Virtual Box (4.3.12).

When starting the Docker script (start_sandbox.sh) I get such errors in output:

Do you see the hostname entry in the /etc/hosts?

# cat /etc/hosts | grep sandbox
172.17.0.2    sandbox.hortonworks.com

# hostname -f
sandbox.hortonworks.com

.

vagrant@sandbox:~$ cat /etc/hosts | grep sandbox
127.0.0.1  sandbox.hortonworks.com sandbox.hortonworks.com vagrant-ubuntu-trusty-64 vagrant-hadooop.vagrantup.com localhost

vagrant@sandbox:~$ hostname -f
sandbox.hortonworks.com

Have you edited the /etc/hosts file manually ?

The entry should not end with localhost. Also localhost need not be mapped with the sandbox.hortonworks.com

See Example from my Sandbox HDP 2.5 default setting: "/etc/hosts"

127.0.0.1       localhost
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.2      sandbox.hortonworks.com

.

@Jay SenSharma

I was editing it manually. Changed as you have proposed:

cat /etc/hosts 127.0.0.1 localhost

# The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts

172.17.0.2 sandbox.hortonworks.com

But still got the same error
