different hosts. JOB Generation and Operation The simple process of job generation is as follows 1. The application first creates an instance of Sparkcontext, such as an instance of SC2. Use an instance of Sparkcontext to create a build RDD3. After a series of transformation operations, the original RDD is converted into other types of RDD4. When the action is applied to the RDD after conversion, the Sparkcontext Runjob method 5 is called. The Sc.run

It is only pointed out that although multiple bytes are used to represent a symbol, the Chinese character encoding of the GB class has nothing to do with the Unicode and UTF-8 of the subsequent text. 3.

I have never figured out what the Unicode Character Set and uft-8 encoding are like in The ascall character set. Article I understand a little bit. Unicode (Computer) The most common standard character set after ASCII. ASCII is still the foundation of computer operation. However, there are too few. It cannot keep pace with the development of computer applications. Unicode is more powerful. The first 255 Unicode characters can be mapped to the ASCII two table. In April 1984, ISO/IEC JTC1/

256 types of symbols. It must be expressed by multiple bytes. For example, the common encoding method for simplified Chinese is gb2312, which uses two bytes to represent a Chinese character. Therefore, it can theoretically represent a maximum of 256x256 = 65536 characters. The issue of Chinese encoding needs to be discussed in a specific article. This note does not cover this issue. It is only pointed out that although multiple bytes are used to represent a symbol, the Chinese character encodi
