HDFS
The distributed file system of Apache Hadoop, designed to store extremely large data sets on commodity hardware while providing high-throughput data access. It serves as the foundational storage layer of the big data ecosystem.
Timeline (last 90 days)
In HDFS anomaly detection, after using structured questioning (computing lifecycle_summary and changing the question to 'is the lifecycle complete'), Decision-1 reached 86% calibrated accuracy on 1200 test blocks (threshold 0.15), with AUC reaching 0.964.
The HDFS default replication factor is 3, meaning each data block is written to three different DataNode nodes, ensuring data remains available when a single node fails.
