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

InputDemuxer
InputDemuxer dem-ultiplexes the input files into individual input
streams. |
JhCounter |

JobHistoryParser
JobHistoryParser defines the interface of a Job History file parser. |
JobHistoryParserFactory.VersionDetector |
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 |
LoggedJob.JobType |
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 rebuilds the cluster topology using the information
obtained from job history logs. |
