AbstractClusterStory AbstractClusterStory provides a partial implementation of ClusterStory by parsing the topology tree.
CDFRandomGenerator An instance of this class generates random values that confirm to the embedded LoggedDiscreteCDF .
ClusterStory ClusterStory represents all configurations of a MapReduce cluster, including nodes, network topology, and slot configurations.
DeepCompare Classes that implement this interface can deep-compare [for equality only, not order] with another instance.
DeepInequalityException We use this exception class in the unit test, and we do a deep comparison when we run the

JobStory JobStory represents the runtime information available for a completed Map-Reduce job.
JobStoryProducer JobStoryProducer produces the sequence of JobStory's.
JobTraceReader Reading JSON-encoded job traces and produce LoggedJob instances.
LoggedDiscreteCDF A LoggedDiscreteCDF is a discrete approximation of a cumulative distribution function, with this class set up to meet the requirements of the Jackson JSON parser/generator.
LoggedJob A LoggedDiscreteCDF is a representation of an hadoop job, with the details of this class set up to meet the requirements of the Jackson JSON parser/generator.
LoggedJob.JobPriority

LoggedLocation A LoggedLocation is a representation of a point in an hierarchical network, represented as a series of membership names, broadest first.
LoggedNetworkTopology A LoggedNetworkTopology represents a tree that in turn represents a hierarchy of hosts.
LoggedSingleRelativeRanking A LoggedSingleRelativeRanking represents an X-Y coordinate of a single point in a discrete CDF.
LoggedTask A LoggedTask represents a [hadoop] task that is part of a hadoop job.
LoggedTaskAttempt A LoggedTaskAttempt represents an attempt to run an hadoop task in a hadoop job.
MachineNode MachineNode represents the configuration of a cluster node.
MachineNode.Builder Builder for a NodeInfo object
Node Node represents a node in the cluster topology.
Outputter Interface to output a sequence of objects of type T.
ParsedJob This is a wrapper class around LoggedJob.
ParsedTask This is a wrapper class around LoggedTask.
ParsedTaskAttempt This is a wrapper class around LoggedTaskAttempt.
Pre21JobHistoryConstants.Values This enum contains some of the values commonly used by history log events.
RackNode RackNode represents a rack node in the cluster topology.
ResourceUsageMetrics Captures the resource usage metrics.
RewindableInputStream A simple wrapper class to make any input stream "rewindable".
TaskAttempt20LineEventEmitter
TaskAttemptInfo TaskAttemptInfo is a collection of statistics about a particular task-attempt gleaned from job-history of the job.
TaskInfo
TreePath This describes a path from a node to the root.
ZombieCluster ZombieCluster rebuilds the cluster topology using the information obtained from job history logs.
ZombieJob ZombieJob is a layer above LoggedJob raw JSON objects.
