Notes: Installing single/multi node hadoop cluster on ubuntu 12.04

Posted on by

1. Installing java6

cd ~/ wget https://raw.github.com/flexiondotorg/oab-java6/master/oab-java6.sh; chmod +x oab-java6.sh; sudo ./oab-java6.sh

Script will build packages from source and place them in local repo, then they can be installed e.g.:

sudo apt-get install sun-java6-jdk sun-java6-fonts sun-java6-source

You can see all available packages in /var/local/oab/deb

Remember to select the right version:

sudo update-alternatives --config java

To setup everything else (like browser plugin, keytool, etc.) you can use this (it will be a long list!)

Reference :- https://github.com/flexiondotorg/oab-java6

Once your done with your java6 installation just follow instructions below links just leave the java installation part from the doc.

Ubuntu Developer Summit and Me

Posted on by

Attending UDS has been one of the biggest thing happened to me in year 2012 i would say so far. :)

Its really great to finally meet people face to face with whom you have been interacting all this while on IRC.

I attended/participated most of the talks on server/cloud/juju during week long conference. I also attended Ubuntu Cloud Summit and was great interacting folks from big cloud based enterprises and to know about there big plans on cloud.

Spent good time with  marcoceppi in the juju room to learn tricks and pieces of juju, i have few more charms in my shoulder. It will be pushed soon to launchpad. :D

I also met Obino and Hspencer from Eucalypus and folks from Cloudstack and Mysql apart from many others. It was great interacting with them all.

I have been telling this all this while Cloud is big and there is room for everyone, the one innovates faster and gets community/support along with gains the most. :)

And last night was total fun, honestly its first time i participated in Karaoke and i did well. :)

I have uploaded photographs i took during the summit at Google+  

Last not the least thanks to Canoanical for sponsoring me to UDS and giving me opportunity to be part of such awesome ecosystem.
