I am totally new to hadoop and didn't do much programming before. I just installed cloudera quickstart via virtualbox. Hue always give me the same message:

Also try clicking Cloudera Manager. It seems like loading forever...

I followed the solution (http://gethue.com/how-to-configure-hue-in-your-hadoop-cluster/) but it seems that I cannot change hdfs-site.xml and core-site.xml directly.

Anyone can help me solve this problem? Any suggestion would be great. Thanks
