To process the huge volume of data in Hadoop cluster MapReduce framework is used. MapReduce is a framework which is written in Java. To get meaningful information from the data you have to write code in terms of map and reduce logic. Map phase performed parallelly on different nodes where as reduce phase aggregates the output from different map phase. Map and Reduce phase is driven by the Driver code. MapReduce code can be written in Java, C++, Ruby, and Python. I am a Hortonworks certified Hadoop Developer. http://bcert.me/swfssczm read less

Hello, I have completed B.com , MBA fin & M and 5 yr working experience in SAP PLM 1 - Engineering documentation management 2 - Documentation management Please suggest me which IT course suitable to my career growth and scope in market ? Thanks.
If you think you are strong in finance and costing, I would suggest you a SAP FICO course which is definitely always in demand. if you have an experience as a end user on SAP PLM / Documentation etc, even a course on SAP PLM DMS should be good.
