Network issues with sandbox

Hi,

I just downloaded the Hortonworks 2.2 VMWare Sandbox (running on Windows 7 x64). All settings are left as default, except I raised the RAM to 8192MB. It runs fine and I’m able to access the Hue interface.

I want to experiment with Flume and Hortonworks (following this tutorial: http://hortonworks.com/hadoop-tutorial/how-to-refine-and-visualize-server-log-data). First I need to install flume. I logged in via ssh and ran:

yum install –y flume

I get this result:

[root@sandbox ~]# yum install -y flume
Loaded plugins: fastestmirror, priorities
Setting up Install Process
Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infra=stock error was
14: PYCURL ERROR 6 - "Couldn't resolve host 'mirrorlist.centos.org'"
Error: Cannot find a valid baseurl for repo: base

I can’t figure out what’s causing the issue. I cannot access any external websites (ping google.com shows unknown host), so I’m thinking it’s a network issue. My VM network connection is set to NAT.

Who can help?
