How to check what version of Sandbox I downloaded?

[#1]

As of HDP 2.3 Sandbox, there is now a another way to determine the version of Sandbox being used. Previously, comparing md5 checksums was one way to compare versions of Sandboxes. Now, one can use the command

sandbox-version

Running the command in the terminal will output a result such as

[root@sandbox azure]# sandbox-version

This is useful when posting issues in the HDP forums regarding the Sandbox.

If you have Ambari running in a browser, you can check the versions of all components of the stack and the HDP version. Also, the version is in the filename of the sandbox VM file.

Without exact science, you can get the version of HDP running on the sandbox, checking the repo enabled on the sandbox:

```yum repolist | grep HDP```
