Subject RE: [VOTE] Release Mahout 0.5, take 2
Date Wed, 25 May 2011 16:10:25 GMT
I've run this many times and it is a hard failure for me. The missing file is really missing
in each run. Cannot run any of these from the CLI for some reason I don't understand:

[dev@devbox mahout]$ ./bin/mahout org.apache.mahout.clustering.display.DisplaySpectralKMeans

Run again and it won't happen. I've seen this infrequently. I don't see it
now nor see Jenkins failures. I believe it is mere test flakiness which is a
bug though not a blocker.
