Hi,
Will mahout 0.4 be released used hadoop 0.20.2 or 0.19?

Huh? k-means, and all other algorithms except maybe classification,
have been converted to 0.20.2

Sorry, I got it. It definitely used 0.20.2 hadoop api. I was wrong.
When I checked kmeans source code, I still have some questions. It seems use
fs to read cluster file from hdfs in every iteration process of map process.
see:
KMeansUtil.java line 73
reader = new SequenceFile.Reader(fs, path, conf);
Doesn't it a better way to use distributed cache?
Thank you, guys.

Are you looking at the current trunk?

But many algorithms still used 0.19 api, for example k-means.
Is there any plan to re-write this algorithm one by one?

Mahout currently depends on 0.20.2, and the new 0.20.x api is used in
many cases, so 0.19 is no longer an option for 0.4
