| org.apache.hadoop.tools.rumen |
Rumen is a data extraction and analysis tool built for
Apache Hadoop.
|
| Class | Description |
|---|---|
| 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. |
| JobConfPropertyNames | |
| 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. |
| LoggedTaskAttempt.SplitVectorKind | |
| 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.
|
| ParsedHost | |
| 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 |
