Hadoop is not suited for real time applications

Unless you go beyond the current standard semantics, this is true.

See here: http://code.google.com/p/hop/  and
http://labs.yahoo.com/node/476for alternatives.

Hadoop consists of several components.
Components like HDFS and HBase are quite suitable for "interactive"
solutions (as in: I usually get an answer within 0.x seconds).
If you really need "realtime" (as in: I want a guarantee that I have
an answer within 0.x seconds) the answer is: No, HDFS/HBase cannot
guarantee that.
Other components like MapReduce (and Hive which run on top of
MapReduce) are purely batch oriented.

Hi,

Thanks for the clarification.

Uhm...

'Realtime' is relative.

Facebook uses HBase for e-mail, right? Now isn't that a 'realtime' application?
;-)

If you're talking about realtime as in like a controller? Or a systems of record for a stock exchange? That wouldn't be a good fit.

'cause email is a soft real-time system.
A bank application would be a hard real-time system.

All the difference is in guarantees.
