Re: HDFS: the subset of posix it implements
Dunno *why* it waited for me to get you an upvote Steve.
I've *read* part of the code, since there is an app team in my shop that thinks HDFS is a good place for SAS temp files and report data.
Update, edit are not options on HDFS in large scale - I noticed the hook for object stores, but even there it looks to me that its more worm style than anything else.
Explaining that HDFS doesn't do these things takes some time - especially with some of the moronic marketing crap out there. (I've seen stuff that should have made the sales techs blush..... and I think I may have made one or two of them actually blush.)
