Uses of Class
org.apache.hadoop.mapred.Counters

Packages that use Counters

org.apache.hadoop.mapred	A software framework for easily writing applications which process vast amounts of data (multi-terabyte data-sets) parallelly on large clusters (thousands of nodes) built of commodity hardware in a reliable, fault-tolerant manner.
org.apache.hadoop.mapreduce

Uses of Counters in org.apache.hadoop.mapred

Methods in org.apache.hadoop.mapred that return Counters

static Counters	Counters.fromEscapedCompactString(String compactString) Convert a stringified counter representation into a counter object.
Counters	RunningJob.getCounters() Gets the counters for this job.
Counters	TaskStatus.getCounters() Get task's counters.
Counters	TaskReport.getCounters() A table of counters.
Counters	JobInProgress.getJobCounters() Returns the job-level counters.
Counters	JobTracker.getJobCounters(JobID jobid)
Counters	LocalJobRunner.getJobCounters(JobID id)
static Counters	Counters.sum(Counters a, Counters b) Convenience method for computing the sum of two sets of counters.

Methods in org.apache.hadoop.mapred with parameters of type Counters

boolean	JobInProgress.getCounters(Counters result) Returns the total job counters, by adding together the job, the map and the reduce counters.
boolean	JobInProgress.getMapCounters(Counters counters) Returns map phase counters by summing over all map tasks in progress.
boolean	JobInProgress.getReduceCounters(Counters counters) Returns map phase counters by summing over all map tasks in progress.
void	Counters.incrAllCounters(Counters other) Increments multiple counters by their amounts in another Counters instance.
static void	JobHistory.JobInfo.logFinished(JobID jobId, long finishTime, int finishedMaps, int finishedReduces, int failedMaps, int failedReduces, Counters mapCounters, Counters reduceCounters, Counters counters) Log job finished.
static void	JobHistory.ReduceAttempt.logFinished(TaskAttemptID taskAttemptId, long shuffleFinished, long sortFinished, long finishTime, String hostName, String taskType, String stateString, Counters counter) Log finished event of this task.
static void	JobHistory.MapAttempt.logFinished(TaskAttemptID taskAttemptId, long finishTime, String hostName, String taskType, String stateString, Counters counter) Log finish time of map task attempt.
static void	JobHistory.Task.logFinished(TaskID taskId, String taskType, long finishTime, Counters counters) Log finish time of task.
void	TaskStatus.setCounters(Counters counters) Set the task's counters.
static Counters	Counters.sum(Counters a, Counters b) Convenience method for computing the sum of two sets of counters.
