C ++ binary input/output stream interface design, binary input/output When it comes to input and output streams, as CPPer, it is natural to think of std: iostream. For text stream processing, iostream can be said to be powerful enough to deal with

Take the file stream as an aspect. Read the source code in the hadoop source code org. Apache. hadoop. FS package. The stream can be divided into two types: input stream and output stream. The following is a simple classification of two types for

After more than a year of plug-in Development, I am familiar with the working mechanism of plug-ins. During the development of plug-ins, I used np_entry.cpp, npn_gate.cpp, npp_gate.cpp, and pluginbase In the sdk. h these files greatly improve the

In this section we will delve into the filesystem class of Hadoop-an important interface for interacting with the file system of Hadoop. While we are only focusing on the implementation of HDFS, we generally pay attention to the portability of code
