Subject Grumble about (lack of) warning of deprecation of Canopy KMeans
Date Fri, 18 Apr 2014 21:47:18 GMT
I was taken aback  that the immensely touted and convenient Canopy
KMeans package was today deprecated [1] in the incubating  mahout 1.0
with no hint that I could find warned in this, at least back through
March. And even then I can  see only in retrospect that a suggestion
lurked in [2] that Streaming KMeans is preferable.  I only saw this
when, in tinkering with my apparently successful use of CanopyDriver,
I ended up in the JavaDoc from the SVN repo, which is where a public
document [3] directs developers.

At the very least, [4] should begin with a deprecation warning (I
commented  Jira MAHOUT-1513 to this effect). Also,  perhaps [3] should
point to the most released JavaDoc rather than the SVN trunk.

Apologies for the grumble if in fact I missed a warning posted here
and I redirect my grumble at myself.
