Thanks so much Pragnesh, for putting your finger so succinctly on the problem. I'm cross-posting this to user@ so that it will be part of that searchable archive too. I will also append to MAHOUT-504.

I'm glad to hear you are out of the woods on this,
Jeff

finally I am able to run kmean example of Clustering of synthetic control data.

I think problem is "hadoop is running as hadoop user(using cloudera
cdh3) and I am trying to run example as pragnesh user"

so hadoop is not able find the under "/user/hadoop"

since example is using relative path to store the input and clustering data.

  Hi Pragnesh,

I really don't know what to suggest to you. I just did a new Mahout checkout
and build, followed by uploading the synthetic_control.data file to a local
Hadoop instance. The k-means job ran without incident. On a hunch, I also
uploaded the file as testdata (not in directory testdata) and that worked
too. I'm baffled why I can't duplicate this and suspect it is a local system
issue. What OS are you running?

If yours works from Eclipse but not from the command line, I wonder if you
have done mvn clean build from the command line before you ran the CLI
Mahout job? Eclipse compiles its bits int

o different directories and does
not build the necessary job files. Other than that, I suggest checking your
file system groups and permissions.

If you find something that gets you running again, *please* post your
solution so we can advise others who are experiencing the same error
message.

this run fine from eclipse

but when i try to run from command line with hadoop. i see following
output.

I tried the Kmeans algorithm on the Synthetic Control data. The following
error appears. I tried the Canopy algorithm, it is fine. This error is from
Mapper. I am using Trunk.
