saveVersion script includes an additional \r while running whoami under windows
-------------------------------------------------------------------------------
Key: HADOOP-7038
URL: https://issues.apache.org/jira/browse/HADOOP-7038
Project: Hadoop Common
Issue Type: Bug
Components: build
Environment: Windows 7 / Eclipse
Reporter: Wang Xu
Assignee: Wang Xu
Priority: Minor
I built common under windows occasionally, and found it failed because the
'user' in build/src/o/a/h/package-info.java is "myhostmyname^M".
It seems because the whoami of windows give a string with '\n\r' rather than
'\n' only. thus I add an additional tr for it to eliminate the problem.
Since only windows would generate '\n\r' output, I think it won't harm to any
other platform.
