Hi Kho, did you manage to get past this error or issue? I just downloaded HDP 2.5 sandbox (11.1GB) from the following link: https://s3.ap-south-1.amazonaws.com/hwx-sandbox-distribution-apsouth1/images/HDP_2.5_vmware.ova and a VM Player version 12 (selected HOST only instead of NAT). Imported the sandbox, and selected the second CentOS 7 image. Booted successfully iun 12-15 mins. (I am using Thinkpad w530, allocated 4GB out of 8GB RAM max I have, core i7, speed 2.65 GHz, 4th gen processor) ... everything worked like a charm! I think your sandbox image is "incomplete". Try to re-download the image from that link which I received from Hortonworks guy yesterday! I am a novice and exploring HDP! ... View more

I have tried this just now after what "indrajeet gour Nov 17, 2016 at 07:21 PM suggested." What you do is: In your VM Player 12 and HDP 2.5, login using root / hadoop credentials. Then use passwd command and change the password to laurent1 (for example). Exit. Re-login using root / hadoop in VM Player. It will not allow you because you changed the password. Re-login using laurent1 password, it will work! You can use the new credentials for Putty SSH port 22 and port 2222. Default maria_dev and raj_ops get eliminated because of passwd command. You can also use ssh xxx.xxx.xxx.xxx -p 22 or 2222 with new password laurent1. It will work. ... View more

This was very useful! I am able to change the password from hadoop to something else and exit from shell and relogin with new password. Thanks for this Indrajeet! ... View more
