Hi everyone,
I want to discuss a question and described as following:
what is the differences between hdfs and kfs(kosmos file system)?
Thanks in advance.

+1. Though our employers may spar on blog posts, as developers we
still get along pretty well for the most part. Let's keep it that way
:)
Back to work.

Guys,
I'm sorry. I really couldn't resist. :-)
Yeah, Arun is right. I've given grief to a couple of vendors making claims about their products.
It was just too easy and well... it's a Monday so I hope everyone took my post with its intended humor value.
We now return you back to the original rant on distributed file systems.

Agree with Cos completely.
As Apache Hadoop becomes more successful, we can expect more of these marketing messages from all sorts of vendors on Apache lists.
Of course it's preaching to the choir when it comes to Mike - I've seen him make similar arguments against other vendors on various forums (LI etc.)... so, thanks Mike! :)

Mike,
I am not speaking for Owen in any way and appreciate your sense of humor, but
the position he has expressed was (and hopefully remain) a stance of these
lists: they aren't a marketing materials distribution channels. These are dev.

Owen,
Are you still a bit touchy over Mike Olson's rebuttal to your blog? :-P

I am going to start advocating FAT32. I think it is undervalued, cross
platform and now even supports both upper and lower case text in
filenames, filenames that can now be more than 8 chars long.

The biggest difference is that kfs is not very active (but not quite dead!)
and hdfs has a pretty active development community.
If you are looking for a file system that has all the virtues of kfs (fast
implementation, fancier file semantics like update) as well as better
performance than hdfs and some whacking cool things like snapshots and
mirrors, check out MapR. (I bet nobody knew I would say that)
