hadoop failed to build from source

I think your environment is missing FINDBUGS_HOME. You can download and install findbugs from here.

After that, you should run following to define FINDBUGS_HOME:

export FINDBUGS_HOME=/path/to/findbugs/installation

Now, your build should not fail due to missing FINDBUGS_HOME environment variable.

I have solved by following commands:

 mvn clean
 mvn compile -Pnative
 mvn package
 mvn compile findbugs:findbugs
 mvn install
 mvn package -Pdist,docs,src,native -Dtar
