[Rumen] Rumen anonymizer should handle composite string data
------------------------------------------------------------
Key: MAPREDUCE-3581
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3581
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: tools/rumen
Affects Versions: 0.24.0
Reporter: Amar Kamat
Assignee: Amar Kamat
Fix For: 0.24.0
Rumen's Anonymizer currently considers string as a single entity. At times,
strings can be composed of smaller sub-strings which can be anonymized
individually. Anonymizing sub-strings separately will result in retaining
certain statistics like frequency ('daily', 'weekly' etc). This was brought up
by Chris while developing the Anonymizer.
