Edward Capriolo reopened HADOOP-6664:
-------------------------------------


In the future, can you please not close a ticket before I even have a chance to 
reply.

1) the generated documentation on the site is wrong. 
2) the generated xml files in the src directory are putting variables in the 
wrong files.

People who are not 'In the know' will put configuration variables in the wrong 
file and not get the effect they desire. 

> fs.inmemory.size.mb not listed in conf. Cluster setup page gives wrong advice.
