## org.apache.hadoop.util
Class Progress

    java.lang.Object
      org.apache.hadoop.util.Progress

    public class Progress

extends Object

Utility to assist with generation of progress reports. Applications build a hierarchy of `Progress` instances, each modelling a phase of execution. The root is constructed with `Progress()`. Nodes for sub-phases are created by calling `addPhase()`.

Constructor Summary
`Progress()` Creates a new root node.

Method Summary
`Progress` | `addPhase()` Adds a node to the tree.
`Progress` | `addPhase(String status)` Adds a named node to the tree.
`void` | `complete()` Completes this node, moving the parent node to its next child.
`float` | `get()` Returns the overall progress of the root.
`Progress` | `phase()` Returns the current sub-node executing.
`void` | `set(float progress)` Called during execution on a leaf node to set its progress.
`void` | `setStatus(String status)`
`void` | `startNextPhase()` Called during execution to move to the next phase at this level in the tree.
`String` | `toString()`
