Subject Locks in hadoop
Date Fri, 16 Jan 2009 01:44:26 GMT
I would like to implement a  locking mechanism across the hdfs cluster
I assume there is no inherent support for it

I was going to do it with files. According to my knowledge, file 
creation is an atomic operation. So the file-based lock should work.
I need to think through with all conditions but if some one has better 
idea/solution, pl share
