Hi,
I'm trying to run the Kmeans example of Hama.The args is
"file:///home/hadoop/file/kmeans/kmeansinput
file:///home/hadoop/file/kmeansoutput 5 5 -g 5 5". What's more , the attach is
"kmeansinput.txt".But I got the problem as follows:
14/01/09 16:38:52 WARN fs.FSInputChecker: Problem opening checksum file:

And "cen.seq" is empty.There might be old checksum files in your HDFS or
local filesystem.But I don't how to clean them up.
Could you help me to solve this problem?
Thanks.
Best wishes.
