What is the impact of small files on Hadoop cluster performance, and how is it mitigated?
- Decreased Latency
- Improved Scalability
- Increased Throughput
- NameNode Overhead
Small files in Hadoop can lead to increased NameNode overhead, affecting cluster performance. To mitigate this impact, techniques like Hadoop Archives (HAR) or combining small files into larger ones can be employed. This reduces the number of metadata entries and enhances overall Hadoop cluster performance.
