I'm glad to hear it helped. This page describes the contribution process.
https://wiki.apache.org/hadoop/HowToContribute For a documentation-only patch on BUILDING.txt, the process would be simplified, because a few steps like unit tests won't be applicable. --Chris Nauroth From: Zheng Huang <bup...@gmail.com<mailto:bup...@gmail.com>> Reply-To: "user@hadoop.apache.org<mailto:user@hadoop.apache.org>" <user@hadoop.apache.org<mailto:user@hadoop.apache.org>> Date: Thursday, November 5, 2015 at 11:51 PM To: "user@hadoop.apache.org<mailto:user@hadoop.apache.org>" <user@hadoop.apache.org<mailto:user@hadoop.apache.org>> Subject: Re: build hadoop source code errors it work , thank you ,very happy for submitting path . but I am a student, don't know how to submit path , could you give me some docs about patch of hadoop project.

I have mine set to the base directory of my Findbugs 1.3.9 installation. > echo $FINDBUGS_HOME /Users/chris/findbugs-1.3.9 I expect setting up this environment variable, pointed to your own Findbugs 1.3.9 installation, would resolve the problem. Perhaps this isn't documented clearly enough in the BUILDING.txt file. We do mention the need for Findbugs 1.3.9, but I don't see mention of needing the FINDBUGS_HOME environment variable. If you're interested in helping to improve the documentation, then we'd welcome a patch on the BUILDING.txt file. I hope this helps. --Chris Nauroth From: Zheng Huang <bup...@gmail.com<mailto:bup...@gmail.com>> Reply-To: "user@hadoop.apache.org<mailto:user@hadoop.apache.org>" <user@hadoop.apache.org<mailto:user@hadoop.apache.org>> Date: Thursday, November 5, 2015 at 10:19 PM To: "user@hadoop.apache.org<mailto:user@hadoop.apache.org>" <user@hadoop.apache.org<mailto:user@hadoop.apache.org>> Subject: build hadoop source code errors HI all, build hadoop source cod have an error after clone hadoop from trunk branch of github.com<http://github.com/>. a commant is mvn package -Pdist,native,docs,src -DskipTests -Dtar on ubuntu:14.10 ppc64le os errors is below:Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (site) on project hadoop-common: An Ant BuildException has occured: stylesheet /home/opuser/project/hadoop_build/hadoop-common-project/hadoop-common/${env.FINDBUGS_HOME}/src/xsl/default.xsl doesn't exist. anyone help me ? thank you .
