-----------------------------------

             Summary: start-build-env.sh behaves incorrectly when username is numeric only
                 Key: HADOOP-16849
                 URL: https://issues.apache.org/jira/browse/HADOOP-16849
             Project: Hadoop Common
          Issue Type: Bug
          Components: build
            Reporter: Jihyun Cho

When username is numaric only, the build environment does not run correctly.
Here is my case.

This is the standard Hadoop Developer build environment.
This has all the right tools installed required to build
Hadoop from source.

I have no name!@fceab279f8d1:~/hadoop$ whoami
whoami: cannot find name for user ID 1112533
I have no name!@fceab279f8d1:~/hadoop$ sudo ls
sudo: unknown uid 1112533: who are you?
{noformat}

I changed {{USER_NAME}} to {{USER_ID}} in the script. Then it worked correctly.
