@Arathy Bhuvaragavamurthy

This error "VERR_VD_VMDK_INVALID_HEADER" indicates that your downloaded Sandbox image in corrupted. So please check the MD5sum result of the image from the Hortonworks site to verify if the MD5sum results are same or not?

https://hortonworks.com/downloads/#sandbox (here you will find the MD5 of different downloaders so after download completes then please check if the downloaded file MD5 is same as mentioned in the mentioned link or not?)

If not then please try downloading the image again.

Also please refer to: https://community.hortonworks.com/questions/27067/vd-error-verr-vd-vmdk-invalid-header-opening-image.html

Thanks @Jay Kumar SenSharma for the quick response. I downloaded the file again and repeated all installation steps and it resolved this issue.

Now. I am able to start the sandbox but it does not complete The System hangs at the step.

Ambari is up and awaiting connection on port 8080

Waiting for ambari services to start.... it screen goes blank after 15 min and I need to restart.

When I tried to look up this issue and it looks like it should be Insufficient memory. I have sufficient hard disc and RAM.

Any suggestion to resolve this issue would be helpful.

I have attached a screen shot of the log sandbox.png

Thanks

Arathy.
