Hi, Imagine I have a very fast hard drive that I want to use for the NameNode. That is, I want the NameNode to store its blocks information on this hard drive instead of in memory.
Why would I do it? Scalability (no federation needed), many files are not a problem, and warm fail-over is automatic. What would I need to change in the NameNode to tell it to use the hard drive? Thank you, Mark
