problems log into Ambari dashboard: unable to start PostgreSQL server

[#1]

Hello,

I am trying to access the ambari dashboard. I am using virtual box to run the hortenworks docker sandbox. I am able to start the virtual machine and log into ports 8888, and 4200, but port 8080 will not work.

I checked the port forwarding options under network settings for the virtual box and 8080 is listed, so I assume that isn't the problem.

I then tried to use the SSH to run the command ambari-server start, but I get an error

using python /usr/bin/python

starting ambari-server

Ambari Server running with administrator privileges.

Running initdb: This may take up to a minute.

About to start PostgreSQL

ERROR: Exiting with exit code 1.

REASON: Unable to start PostgreSQL server. Status None. . Exiting

and I'm not sure what to do next.

What you should do next is post the specific version of the sandbox you are running in this thread so that members of the community who are inclined to do so can address your question. You should also post the specific virtualization platform you're using, as your question mentioned both virtual box and docker; I have to assume you are only actually using one or the other.

If you don't know how to obtain the sandbox version, see this tutorial:

Learning the Ropes of the HDP Sandbox

…and scroll down to the subsection Sandbox Version and follow the instructions there.
