10. Compiled tar package

/ opt/sourcecode/hadoop-2.8.1-src/hadoop-dist/target/hadoop-2.8.1.tar.gz

Reminder:

1. Sometimes it takes too long to download a package during compilation, which is due to fake death in the process of connecting to the website.

Press ctrl+c at this time to rerun the compile command.

2. If a file is missing, clean up maven (use the command mvn clean) before recompiling.
