>
> When a slave component, such as a DataNode, encounters some catastrophic
> problem like a heap allocation error, and no longer can perform its work, the
> NameNode marks this DataNode as being unhealthy.
> The current alert definitions only check for the DataNode process being
> alive, which is still technically is. We need to add new alert definitions
> for:
> - HDFS/DataNode (runs on NameNode, query is to NameNode JMX)
> - YARN/NodeManager (runs on ResourceManager, query is to ResourceManager JMX)
> - HBase/RegionServer (runs on HBase Master, queries HBase Master JMX)
> Which will check for slaves that are in some sort of bad state. Depending on
> the JMX structures that need to be queried, these can either be METRIC or
> SCRIPT style alert definitions.
