Re: Hadoop usage in uploading downloading big data

Thank for your reply. The data is design data. This data is mix of ascii, binary and design views (IPs, libraries, cadence design data etc..). Currently its exactlly the way we use any other repository servers such as svn, git. etc.. (checkin, checkout, add, tag etc...). User stores the data on

Why don't you base your application on ProtobufRpcEngine ? Cheers On Tue, Jun 10, 2014 at 10:42 AM, Anfernee Xu anfernee...@gmail.com wrote: Hi, I'm using hadoop-2.2.0 and take advantage of Hadoop WritableRpcEngine to build my distributed application, and I have 'heartbeat' interface in my
