Subject Re: 回复: fs.FSInputChecker: Problem opening checksum file: file:/home/hadoop/file/kmeans/center/cen.seq

Hi,

TRUNK is a repository that contains latest (unreleased) changes.

Here you can find a tutorial [1] how you can build Hama from TRUNK.
Therefore you will need Subversion (svn) and Maven 3 (mvn).

Kind regards,

Martin
