      This jira adds a new metric with name "StaleDataNodes" under metrics context "dfs" of type Gauge. This tracks the number of DataNodes marked as stale. A DataNode is marked stale when the heartbeat message from the DataNode is not received within the configured time ""dfs.namenode.stale.datanode.interval".


      Please see hdfs-default.xml documentation corresponding to "dfs.namenode.stale.datanode.interval" for more details on how to configure this feature. When this feature is not configured, this metrics would return zero.
