Go uses the "strings" package for string operations. 1) Use strings.Join function to splice strings. 2) Use the strings.Contains function to find substrings. 3) Use the strings.Replace function to replace strings. These functions are efficient and easy to use and are suitable for various string processing tasks.

Go's encoding/binary package is a tool for processing binary data. 1) It supports small-endian and large-endian endian byte order and can be used in network protocols and file formats. 2) The encoding and decoding of complex structures can be handled through Read and Write functions. 3) Pay attention to the consistency of byte order and data type when using it, especially when data is transmitted between different systems. This package is suitable for efficient processing of binary data, but requires careful management of byte slices and lengths.

In Go, the performance problem will be triggered when the map is expanded. The following measures can be avoided: 1. Estimate the map size and set the appropriate initial capacity; 2. Process data in batches to reduce the pressure of single-scaling expansion; 3. Use sync.Map to deal with high concurrency scenarios.

The byte package provides a variety of functions to efficiently process byte slices. 1) Use bytes.Contains to check the byte sequence. 2) Use bytes.Split to split byte slices. 3) Replace the byte sequence bytes.Replace. 4) Use bytes.Join to connect multiple byte slices. 5) Use bytes.Buffer to build data. 6) Combined bytes.Map for error processing and data verification.

There are many methods and tools for monitoring Hadoop clusters on Debian systems. The following are some commonly used monitoring tools and their usage methods: Hadoop's own monitoring tool HadoopAdminUI: Access the HadoopAdminUI interface through a browser to intuitively understand the cluster status and resource utilization. HadoopResourceManager: Access the ResourceManager WebUI (usually http://ResourceManager-IP:8088) to monitor cluster resource usage and job status. Hadoop
