CentOS Platform Hadoop Distributed File System (HDFS) Performance Optimization Guide Optimizing HDFS Performance is a multi-faceted issue, and multiple parameters need to be adjusted for specific situations. The following are some key optimization strategies: 1. Memory management adjusts the NameNode and DataNode memory configuration: reasonably configure the HADOOP_NAMENODE_OPTS and HADOOP_DATANODE_OPTS environment variables according to the actual memory size of the server to optimize memory utilization. Enable large page memory: For high memory consumption applications (such as HDFS), enabling large page memory can reduce memory page allocation and management overhead and improve efficiency. 2. Disk I/O optimization uses high-speed storage
