AbstractClusterStory provides a partial implementation of
ClusterStory by parsing the topology tree.InputDemuxer to a particular file.
MachineNode object.
LoggedDiscreteCDF .MachineNode object.
ClusterStory represents all configurations of a MapReduce cluster,
including nodes, network topology, and slot configurations.LoggedNetworkTopology object.JobHistoryParser that parses JobHistory files produced by
org.apache.hadoop.mapreduce.jobhistory.JobHistory in the same source
code tree as rumen.DefaultInputDemuxer acts as a pass-through demuxer.Outputter that outputs to a plain file.Nodes.
LoggedNetworkTopology object.
JobConf for the job.
LoggedJob object read directly from the trace.
MachineNode by its host name.
TaskAttemptInfo for a given task-attempt, considering impact
of locality.
TaskAttemptInfo with a TaskAttemptID associated with
taskType, taskNumber, and taskAttemptNumber.
JobStory.
JobStory.
RackNode by its name.
TaskStatus.State of the task-attempt.
TaskAttemptInfo for a given task-attempt, without regard to
impact of locality (e.g.
TaskAttemptInfo with a TaskAttemptID associated with
taskType, taskNumber, and taskAttemptNumber.
TaskInfo for a given task.
TaskInfo for the given task-attempt.
JobHistoryParser to parse job histories for hadoop 0.20 (META=1).Outputter to a specific path.
StatePool.
InputDemuxer dem-ultiplexes the input files into individual input
streams.JobBuilder builds one job.JobConfigurationParser parses the job configuration xml file, and
extracts configuration properties.JobHistoryParser defines the interface of a Job History file parser.JobHistoryParserFactory is a singleton class that attempts to
determine the version of job history and return a proper parser.JobProperties parsing utility.JobStory represents the runtime information available for a
completed Map-Reduce job.JobStoryProducer produces the sequence of JobStory's.LoggedJob instances.JsonGenerator to write objects in JSON format.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.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.LoggedLocation is a representation of a point in an hierarchical
network, represented as a series of membership names, broadest first.LoggedNetworkTopology represents a tree that in turn represents a
hierarchy of hosts.LoggedSingleRelativeRanking represents an X-Y coordinate of a
single point in a discrete CDF.LoggedTask represents a [hadoop] task that is part of a hadoop job.LoggedTaskAttempt represents an attempt to run an hadoop task in a
hadoop job.MachineNode represents the configuration of a cluster node.MapTaskAttemptInfo represents the information with regard to a
map task attempt.(state, taskInfo, runtime,
List<List<Integer>> allSplits)
instead.
see LoggedTaskAttempt for an explanation of
allSplits.
If there are no known splits, use null.
HistoryEvent
Node represents a node in the cluster topology.LoggedJob.LoggedTask.LoggedTaskAttempt.HistoryEvent
Properties.
HistoryEvent
Properties.
RackNode represents a rack node in the cluster topology.ReduceTaskAttemptInfo represents the information with regard to a
reduce task attempt.(state, taskInfo, shuffleTime, mergeTime, reduceTime
List<List<Integer>> allSplits)
instead.
see LoggedTaskAttempt for an explanation of
allSplits.
If there are no known splits, use null.
State object.TaskAttemptInfo is a collection of statistics about a particular
task-attempt gleaned from job-history of the job.DefaultAnonymizableDataType
using a WordList for anonymization.ZombieCluster rebuilds the cluster topology using the information
obtained from job history logs.ZombieJob is a layer above LoggedJob raw JSON objects.ZombieJob with the same semantics as the
LoggedJob passed in this parameter
ZombieJob with the same semantics as the
LoggedJob passed in this parameter
JobStorys from job trace.
