First of all, learning big data needs to have the foundation of java,python and R language.

1) at what level can Java learn from big data?

Java needs to learn javaSE. Javaweb,javaee is not needed for big data. Once you learn javase, you can understand the hadoop framework.

2) python is the easiest to learn, the degree of difficulty: python java Scala.

Python is more intuitive and easier to understand than java, because if you know Python, you still have to learn java. You have learned java, and then it will be very easy to learn python. You can learn python in a week.

3) R language can also be learned, but it is not recommended, because java uses the most people. Big data's first framework, Hadoop, was written by Java at the bottom. Even if I learned R, I still can't understand hadoop.

The role of java in big data is to form big data's language, big data's first framework Hadoop and other big data technical frameworks, the underlying language is all written by Java, so it is recommended to learn java first.

Let me give you an example to illustrate their division of labor and role. Java pays attention to business, big data pays attention to data, the front end is the face (page display), java is the arm (business), big data is the straight male brain, artificial intelligence, deep learning is the brain with EQ.

If you want to learn big data well, you'd better join a good learning environment. You can come to this Q Group 251956502 so that it is more convenient for everyone to learn, and you can also communicate and share materials together.

Big data's career development direction

Learned big data, do not need to start from java, can directly do big data development engineer. After accumulating a few years of experience, you can become an algorithm engineer. Take a look at what positions big data can take:

Big data Development engineer

Data analyst

Hadoop Development engineer

Spark Development engineer

Data Warehouse Development engineer

Data cleaning engineer (ETL)

Big data architect

Algorithm engineering

Big data's advantage

Big data is strongly supported by the state and a lot of resources are invested in this area. Big data Center sits in Guizhou. Artificial intelligence and cloud computing are based on big data, which requires a large number of big data talents.

1) big data's salary and treatment for talents

In general, the average monthly salary of big data-related jobs in first-tier cities is 12-15K in Beijing, the average monthly salary is 17K, and the annual salary of big data algorithm engineer is about 300000-500000.

2) do you have any academic / professional requirements to study big data?

I also found a job in high school, but college degree or above is better. Although I have a bachelor's degree, I have not learned practical operational skills in four years of college. What I have learned is not needed at work, but it is easier to understand some things.
