## Uses of Class
org.apache.hadoop.mapred.JobInProgress

Packages that use JobInProgress
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.

Uses of JobInProgress in org.apache.hadoop.mapred

Methods in org.apache.hadoop.mapred that return JobInProgress
`JobInProgress` | `TaskInProgress.getJob()` Return the parent job
`JobInProgress` | `JobTracker.getJob(JobID jobid)`

Methods in org.apache.hadoop.mapred that return types with arguments of type JobInProgress
`Vector<JobInProgress>` | `JobTracker.completedJobs()`
`Vector<JobInProgress>` | `JobTracker.failedJobs()`
`List<JobInProgress>` | `JobTracker.getCompletedJobs()`
`List<JobInProgress>` | `JobTracker.getFailedJobs()`
`List<JobInProgress>` | `JobTracker.getRunningJobs()` Version that is called from a timer thread, and therefore needs to be careful to synchronize.
`Vector<JobInProgress>` | `JobTracker.runningJobs()`

Methods in org.apache.hadoop.mapred with parameters of type JobInProgress
`void` | `JobTracker.failJob(JobInProgress job)` Fail a job and inform the listeners.
`void` | `JobTracker.initJob(JobInProgress job)`

Constructors in org.apache.hadoop.mapred with parameters of type JobInProgress

Methods in org.apache.hadoop.mapreduce.server.jobtracker that return JobInProgress
`JobInProgress` | `TaskTracker.getJobForFallowSlot(TaskType taskType)` Get the `JobInProgress` for which the fallow slot(s) are held.

Methods in org.apache.hadoop.mapreduce.server.jobtracker with parameters of type JobInProgress
`void` | `TaskTracker.reserveSlots(TaskType taskType, JobInProgress job, int numSlots)` Reserve specified number of slots for a given `job`.
`void` | `TaskTracker.unreserveSlots(TaskType taskType, JobInProgress job)` Free map slots on this `TaskTracker` which were reserved for `taskType`.

Method parameters in org.apache.hadoop.mapreduce.server.jobtracker with type arguments of type JobInProgress
