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 !
