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 [1] http://wiki.apache.org/hama/GettingStarted#Build_latest_version_from_source 2014/1/9 步青云 <[email protected]> > Thanks for your so timely reply.By the way,what's TRUNK and how can I use > TRUNK? > Best wishes. > > > > > ------------------ 原始邮件 ------------------ > 发件人: "Martin Illecker"; > 发送时间: 2014年1月9日(星期四) 晚上6:12 > 收件人: "user"; > 主题: Re: fs.FSInputChecker: Problem opening checksum file: > file:/home/hadoop/file/kmeans/center/cen.seq > > > > Hi, > > a patch [1] is available and will be committed into TRUNK shortly. > > Please use the TRUNK. > Thanks for your report. > > Kind regards, > > Martin > > [1] https://issues.apache.org/jira/browse/HAMA-834 > > > 2014/1/9 Martin Illecker <[email protected]> > > > Hi, > > > > sorry for inconvenience, I have reopened a issue [1] to fix this. > > > > The problem exists only when K = N.
