In this post we will know and understand the prerequisites to learn Hadoop. If you want to learn and make your career in Hadoop but do not know from where to start then you will get more questions like as follows.
From where should i start learning Hadoop?
Is java required to learn Hadoop?
What Technologies should know to learn Hadoop?
What is the importance of SQL knowledge in Hadoop?
How would be career growth in Hadoop?
like this you will get many questions before start to learn Hadoop. You will get answers for all questions regarding Hadoop.
What are the prerequisites to learn Hadoop:
If you want to become an expert in Hadoop and make an excellent career, you should have at least basic knowledge of java and Linux. If you don't have any idea on Java and Linux no worries, you still can start learning Hadoop. But Basic Knowledge on Java and Linux is required so spend some time to learn Basics of Java and Linux parallel.
Is Java required to learn Hadoop:
It is added advantage if you have java knowledge. Since you can write your map and reduce functions in the language of your choice. There are some advanced features via the Java API. So knowledge of java comes handy here.
Sometimes,java is not strictly a prerequisites for working with Hadoop. Because there are tools like Hive and Pig that are built on top of Hadoop offer their own High-level languages for working with data on your cluster. If you want to write your own MapReduce code,you can do so in any language like perl,python,c,Ruby etc..
Finally i can conclude with few words,Hadoop projects comes with a lot of different roles like Architect,Developer,Tester,Linux/Network/Hardware Adminstrator and some of which require explicit knowledge of Java and some Don't. If you want become expert in Hadoop then you should have knowledge on Java and Linux.
What are the importance of SQL knowledge in Hadoop:
Now a days, Hadoop is hot new technology,if you are already comfortable with SQL,then learning how to use Hive will feel very familiar as it's syntax and commands are very SQL-like. Hadoop is not replacement for RDBMS and other DataBase.
I know C/C++ is this benefit to learn Hadoop:
Defiantly, Because there are several parts of the Hadoop system that are written in C and C++. If you want write map-reduce code in C++ then Hadoop also has pipes. Here pipes is library which allows C++ source code to be used for Mapper and Reducer code.
If you know C and C++ programming Language then to learn Java is very easy,it is not difficult at all. So learn Java and start learn Hadoop.
How would be Career Growth in Hadoop:
Hadoop is one of the top 10 job trends right now. Microsoft,Oracle and IBM,Amazon,Facebook are also looking for Hadoop Prefessionals. So Your feature must be bright with Hadoop.
I hope you enjoy this post and keep follow me for latest updates on Hadoop and share this post to your friends.
