It feels ecstatic to complete this certification with decent score in first attempt. It was like those struggling days when we used to study hard for our final exams during college...
My preparation started as I joined a new company where i landed in hadoop . I had zero idea about hadoop and was worried how can i excel in this field.As the project demanded Hadoop Mapreduce i first started developing basic MR codes.
Having basic experience in Java helped me , slowly and steadily by solving assignments and reading about hadoop ecosystem I started liking the subject .
Whatever i used to read or understand i would draw the concepts on a paper and publish this on my blog.
Blogging gave me a great booster and i developed more interest of learning by creating or reading blogs.
After gaining good 6 months of knowledge I decided to crack CCD-410 .
So some much needed tips : -
- Have basic exp in Java. OOPS concepts , ETL background (optional)
- Complete study of the Hadoop Definitive guide . Its the bible of Hadoop .
- Clear understanding of all Hadoop Concepts practically and theoretically . Try so write as such MR code.. developing complex key, value pair !
- Yahoo MR Tutorials. . Good for beginners .
- Hadoop ecosystem is huge .. Try to have glimpse of sub projects like Hbase, Hive , pig , Flume ,Oozie , Sqoop.. Study what they do and where can they be useful .
- Try to blog ! blogs are very important . Read as many blogs on hadoop . Best would be create your own BLOG !
- If you are completely new to hadoop and require some training .. you will get many institute who provide it.. I feel Nixus Technologies is coming up well.
- The exam contains the same pattern as discussed here Study Guide . Read the guide and understand which module holds importance .
- If you guys feel weak in MR coding you can download developer simulator from Hadoop Developer Simulator and start solving. Its a very good software and exams questions are very much similar as mentioned in it.
- Have belief and Trust in yourself and Crack It ! All the very Best !

ReplyDeleteHi ,
DeleteYou just need to knw the basic of what all these technology do and when they can be useful . CCDH is more of Mapreduce oriented exam i feel . Very basic questions are asked abt sub projects .
Tc All the best !
Hi Chitrank,
ReplyDeleteWhere from can I get MR assignments or hand on exercises.
Hi ashish ,
ReplyDeleteIf you are already into hadoop development then whatever you are doing must be sufficient .
Otherwise if you need to extra question try hadoopexam.com simulator .
Thanks Chitrank.
DeleteI am not into hadoop development but learning it.
I hope that hadoopexam.com simulator is enough for MR practice.
Hi Chitrank,
ReplyDeleteGreat Blog. Very motivating.
In one your comments above, you speak of reading/writing a blog. Can you shed more light on that. And also, what role has hadoopexam.com played in your journey to becoming a certified developer. Congrats and Thanks in advance..
Hi zahiruddin ,
DeleteIts like when u start learning hadoop , you come across so many concepts . For me learning is thru representing the idea into a diagram which helps me understand easily. Hence i started making diagrams .
This also helped me revise stuff if i forget by just looking at the diagrams .
The idea of blogging stroked because i thought my understanding or diagrams may help others understand concepts easily .
Coming to hadoopexam .. it has surely helped me alot . Question are very much similar to the actual exam .So i recommend it.
All the Best !

I am a beginner in Hadoop and want to be certified (soon).
ReplyDeleteI just wanted your view on 'Hadoop in Action' by Chuck Lam. A lot of people suggest that its a good book written in a simple , clear manner ; however, read a couple of book reviews on Amazon.com which suggest that the book is outdated (as it refers version 0.2 of Hadoop / book released in 2011 and Hadoop world is changing fast etc...).
Does the book help me with certification - are the concepts, examples and coding in the book relevant now ?
hello friend
Deletefor certification read hadoop definitive guide 4th edition and follow cloudera certification site
