DebuggingWordCount (java 2.62.0 API)

java.lang.Object
- org.apache.beam.examples.DebuggingWordCount

```
public class DebuggingWordCount
extends java.lang.Object
```
An example that verifies word counts in Shakespeare and includes Beam best practices.
This class, DebuggingWordCount, is the third in a series of four successively more detailed 'word count' examples. You may first want to take a look at MinimalWordCount and WordCount. After you've looked at this example, then see the WindowedWordCount pipeline, for introduction of additional concepts.
Basic concepts, also in the MinimalWordCount and WordCount examples: Reading text files; counting a PCollection; executing a Pipeline both locally and using a selected runner; defining DoFns.
New Concepts:
```
   1. Logging using SLF4J, even in a distributed environment
   2. Creating a custom metric (runners have varying levels of support)
   3. Testing your Pipeline via PAssert
 
```
To execute this pipeline locally, specify general pipeline configuration:
```
 --project=YOUR_PROJECT_ID
 
```
To change the runner, specify:
```
 --runner=YOUR_SELECTED_RUNNER
 
```
The input file defaults to a public data set containing the text of King Lear, by William Shakespeare. You can override it and choose your own input with --inputFile.
