org.apache.hadoop.mapred to org.apache.hadoop.mapreduce

regarding ```CrawlDbUpdateTestDriver.java:95: warning: [deprecation]
setConfiguration(Configuration) in TestDriver has been deprecated```
please see
[javadoc](https://mrunit.apache.org/documentation/javadocs/1.1.0/index.html?org/apache/hadoop/mrunit/TestDriver.html):
Deprecated. Use getConfiguration() to set configuration items as opposed to
overriding the entire configuration object as it's used internally. Also make
sure to update the Class and Method-level API documentation to ```{@link
CrawlDbReducer#reduce(Text, Iterator, Context)}``` this is present in several
Classes and you have not updated it yet.
regarding ```CrawlDbUpdateUtil.java:58: error: cannot find symbol``` this is
due to removal of ```configure``` method for Reducer.java. Please see
[Javadoc](https://hadoop.apache.org/docs/current/api/org/apache/hadoop/mapreduce/Reducer.html).
You may have to work with ```setup``` instead.
Fix both of the above, which once addressed will bring the compilation back
to stable I think. Also check out the Javadoc for
[TaskInputOutputContext](https://hadoop.apache.org/docs/current/api/index.html?org/apache/hadoop/mapreduce/TaskInputOutputContext.html)
and ensure that CrawlDbUpdateUtil.DummyContext overrides the appropriate
methods with the appropriate peramaters.
