management is certainly not beyond it. However, as we have mentioned, the particularity of the open source software development model also puts forward new and stricter process requirements for its bug tracking and management process. In this case, it is necessary to have a more correct understanding of the defect tracking system (bug Tracker) first. Defects include product errors, requirements and design changes, new features or extensions (Feature,

1.the 3 modes that the Hadoop cluster can run. Single-machine (local) mode pseudo-distributed mode fully distributed mode 2. note points in the stand-alone (local) mode. There is no daemon in stand-alone mode (standalone), and everything runs on a JVM. There is also no DFS here, using the local file system. Stand-alone mode is suitable for running mapreduce programs during development, which is also the least used mode. 3. note points in pseudo-distribution mode. Pseudo-distributed (Pseudo) is
