[@amirkazemi2517]

the recent WSJ article has stated hadoop as being very slow when multiple users are interacting with it. can ssd or flash technology help with large files and huge data sets?

[@gorillawack2393]

loves the funkybeat at the end, hadoop> faster batch processing via mapreducing large datasets. Not good for adhoc queries like relational databases, although some startups are working on such query functions, "hive",
