Use IOUtils, FileLineIterable/Iterator across the project
---------------------------------------------------------
Key: MAHOUT-175
URL: https://issues.apache.org/jira/browse/MAHOUT-175
Project: Mahout
Issue Type: Improvement
Affects Versions: 0.2
Reporter: Sean Owen
Assignee: Sean Owen
Priority: Minor
Fix For: 0.2
Attachments: MAHOUT-175.patch
The patch I will attach does a couple things:
Uses FileLineIterable/Iterator for iterating over lines of a file. This is
slightly tidier, but also addresses a few subtle issues across the code base,
where reading of files did not always end by closing the stream, or, relied on
platform default character encoding.
Uses IOUtils consistently to close Closeables, swallowing and logging
exceptions in cases where they are not to be treated as errors.
Finally, fixes some issues in ARFFIterator while I'm at it -- hasNext() changes
state, when next() should, and next() did not throw NoSuchElementException
