.
Subsequently, one may also ask, is it easy to learn Hadoop?
No Learning Hadoop is not very difficult. Hadoop is a framework of java. Java is not a compulsory prerequisite for learning hadoop. Hadoop is an open source software platform for distributed storage and distributed processing of very large data sets on computer clusters built from commodity hardware.
Subsequently, question is, is it worth to learn Hadoop? Learning Hadoop will definitely give you a basic understanding about working of other options as well. Hadoop provides a good ecosystem to support processing of huge data in a distributed manner. There are several tools (like Spark) which leverage Hadoop environment for lightening fast operations over data.
People also ask, how much time will it take to learn big data?
Ideally, it will take 2–3 months to come up with a good personnel in Big Data. If you are core developer on database or Java, it may take bit less time.
