Description
- What happens to active clients if different nodes die? (namenode, datanode, journalnode)
- How long does detection/recovery take?
- What happens if we permanently lose the data of a node, how can the data be restored? (again, all three)

Research direction
Start by locating the HDFS HA and disaster-recovery documentation entry points in this Antora repository. Research failure and recovery behavior for NameNodes, DataNodes, and JournalNodes, including client impact, detection time, recovery time, and permanent node-data loss. Done means the relevant documentation explains each scenario and restoration path clearly.
