YARN and MRv2: The New Incarnations In The Cloud!


As you all know, MapReduce has undergone a complete overhaul in hadoop-0.23 (or from CDH4 onwards, for the Cloudera fans like me)  and we now have, what we call, MapReduce 2.0 (MRv2 or simply MR2) or YARN. You might have read a lot about the same and I’m not going to explain it all over again here. But I feel a little recapitulation will be useful for all of us.

Like Apache Hadoop MapReduce got a large overhaul and upgrade, there is been a local upgrade here too. Just got in to the lions den last week.

Yep, you heard it correct, Asia’s one of the best Apache Hadoop facility, with all the industry standard amenities for the cloud and a huge number of certified Hadoop developers as colleagues; sure, you can expect industry standard cloud technology write-ups from now on.

To Experience Certainty, Stay tuned…

UPDATE: As of now the upgrade assistant is not working. See the error message the upgrade assistant throwing out while connecting to upgrade offer server.
Windows8 upgrade assistant failed.

UPDATE: Everything working fine as of now, the upgrade assistant went like a breeze and the upgrade process was very quick, got the Windows 8 Pro key within a minute, yup, you guessed it correct, for $14.99. The upgrade assistant is a mini downloader too, after completing the Windows 8 upgrade offer, the upgrade assistant started downloading the OS! That was very nice, but I dismissed the download because the just bought key worked flawlessly with the MSDN image too, so why download the same thing over and again?

For those who are looking for the MSDN image, there are torrents out there, which will get you an untouched virgin image of Windows 8 Pro, from MSDN. Use the same with the key and enjoy the new OS.

As of now there is no confirmed reports that Microsoft is verifying your purchase of PC, so you can register with some seemingly genuine data on https://www.windowsupgradeoffer.com/en-US/ and grab your copy of Windows 8. So what are you waiting for, grab your copy of genuine Windows 8, without wasting time searching for illegal KMS servers. Be genuine, at least for the product key. :)
