CCHD -  Cloudera Certified Hadoop Developer - CDH5

I would like to share some tips on preparing for the cloudera certification. Mostly importantly cloudera exam is now on CDH Version 5. Please note that you should have hands-on experience on CDH5 and also have good exposure to MapReduce programming/design patterns else consider yourself half prepared.  30-40% Questions in the exam were scenario based and Map Reduce programming and Sqool, Hive or File system commands options.  

I suggest to download and install the vm on your machine and practice

If you are very serious about the Hadoop certification, I highly recommend the Cloudera Developer Training for Apache Hadoop
