> Hadoop must have some mechanism to find the health status of a node . It
> should run the health check script periodically and if there is any errors,
> it should black list the node. This will be really helpful when we run static
> mapred clusters. Else we may have to run some scripts/daemons periodically to
> find the node status and take it offline manually.
