It seems I have this problem solved now, but so that I learn more -- how do you safely power down the sandbox? and then to power up, I just do "docker start sandbox" and then ssh in on port 2222? I have tried so many things that I want to walk away with this clarified. So, 1) how to power down and 2) and I correct in how to power up? Thanks! ... View more

Can't believe it was so simple. Argh. Thanks!! ... View more

Looks like it's not: [root@sandbox ~]# ambari-server status Using python/usr/bin/python Ambari-server status Ambari Server not running. Stale PID File at: /var/run/ambari-server/ambari-server.pid [root@sandbox ~]# ... View more

I tried running the script again, per the Sandbox Deployment and Install guide, and it looks like the container is still not running: Loris-MacBook-Pro:Desktop lorihurley$ docker start sandbox sandbox Loris-MacBook-Pro:Desktop lorihurley$ sh start_sandbox-hdp2.sh Waiting for docker daemon to start up: ba112ddd357esandbox-hdp "/usr/sbin/sshd -D" 2 weeks ago Exited (255) 2 weeks agosandbox-hdp Error response from daemon: driver failed programming external connectivity on endpoint sandbox-hdp (c4f0630e5c909893ef7fee6ea8f4d8644238a9dd4a38b3da3168c8d0880f786f): Bind for 0.0.0.0:60080 failed: port is already allocated Error: failed to start containers: sandbox-hdp Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Waiting for ambari agent to connect Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Waiting for ambari services to start Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Error response from daemon: Container ba112ddd357e3a08eb7fe253d5d8a8749c34970d25fe312635c04693d8a1147f is not running Loris-MacBook-Pro:Desktop lorihurley$ ...

I added comments above. I have reinstalled the image. I think I deleted it from my downloads at some point, because I thought if it was loaded into Docker, it was loaded into Docker. Can you confirm this is true or not -- that I need to keep the tar file on my laptop? Because now that I have downloaded it again and reinstalled, I'm still getting the connection error. Also, when you say start and stop the image, do you just mean command line "docker start sandbox" and how to stop? I'm a newbie -- thanks for all your help!! ... View more

I did the image reinstalled and did do as you said deleting the info from known_hosts. Now I get the original connection refused error: [root@sandbox ~]# ssh root@127.0.0.1 -p 2222 ssh: connect to host 127.0.0.1 port 2222: Connection refused ... View more

@Ramesh Prasad @Jay SenSharma @Sonu Sahi Thanks for your help. Looks @like my image is gone. No clue how that happened 😞 Trying to download again, but it keeps canceling. I imagine it will be problematic to try to install it now since it was installed previously? Argh. ... View more
