Hi,

Need help on finding good consultancies to get started with Hadoop Training? Please provide some information.

Udacity.com , they have very nice online training program for Big Data Hadoop but its not a consultancy though.

I would recommend Udacity.com too. Another popular one is Coursera.org, they have very good lecture series specially:

Web Intelligence and Big Data from IIT
Introduction to Data Science from Washington University in Seattle
Designing and Executing Information Security Strategies from Washington University in Seattle
Scientific Computing Washington University in Seattle

Hadoop is really a hot - topic in market these days (even for past 1 and half years). I believe most of the developers use JAVA based API. If you are fluent in developing JAVA applications then the next step up is Hadoop.
Good Luck.

Thank you for the responses.
But I would precisely like to know the consultancies if possible.

http://www.dfwtechnology.com/ , dont know how effective  is their training program and placement system but lately I hear advertisement of their Hadoop training program on Deshi FM radio so often.
