[jira] [Created] (MAHOUT-661) Finish iterator overhaul by using
Google Guava
Finish iterator overhaul by using Google Guava
----------------------------------------------
Key: MAHOUT-661
URL: https://issues.apache.org/jira/browse/MAHOUT-661
Project: Mahout
Issue Type: Improvement
Components: Classification, Clustering, Collaborative Filtering, Frequent Itemset/Association Rule Mining, Utils
Affects Versions: 0.4
Reporter: Sean Owen
Assignee: Sean Owen
Priority: Minor
Fix For: 0.5
To complete this truly interesting overhaul of the use of Iterator -- I rightly guessed that Guava already has some of these common classes and more. Indeed. I can see easily another 1,000 lines of code of savings by adapting to use their iterator primitives. I'm in progress now and have removed 600 lines so far. I think this will go a long way to avoiding subtle and various bugs in the iterator implementations to date. I can definitley get it in before 0.5.

-----------------------------
Attachment: MAHOUT-661.patch
Nicely, it removes a net 1100 lines of code.
This also uses Charsets.UTF_8 as a bonus.
