Hi Manoranjan, While knowing Java will help you better use more of the features of Hadoop and process the data more efficiently, I have worked in a situation where we used Hadoop without touching any Java code at all. We needed to utilise our legacy Perl code in our Map-Reduce jobs and simply used the Hadoop streaming. With tools like Whirr you can completely use Hadoop as a blackbox if you need to. http://www.slideshare.net/philwhln/map-reduce-using-perl http://www.philwhln.com/map-reduce-with-ruby-using-hadoop
But, as a "data architect" I think knowing Java is important. Not just for Hadoop, but for all the other Apache projects that focus on managing data, are built with Java and providing Java APIs (ActiveMQ, Cassandra, Lucene / Solr, HBase, Hive, Mahout...).
