Data node availability (Availability)
This parameter indicates if the DataNode is down or up. If the KM fails to find the DataNode in the live nodes of NameNode then it will set its status to Not Ok, else will set the status to Ok. If the KM monitors DataNode with direct connection, and if it fails to connect to the DataNode JMX Url then the status will be set to Not Ok. If the connection is not direct and it uses the parent node, then it will set the status to Partial.
