Description

• When running ./bin/hadoop in cygwin, we see an error message from cypath.
  For example,

  bash-3.2$ ./bin/hadoop namenode -format
  cygpath: cannot create short name of :\cygdrive\d\@sze\hadoop\latest\hadoop-*-tools.jar:\cygdrive\d\@sze\hadoop\latest\build\hadoop-*-tools.jar
  ...
  

• The output message is confusing for incorrect commands.
  For example,

  bash-3.2$ ./bin/hadoop foo
  cygpath: cannot create short name of :\cygdrive\d\@sze\hadoop\latest\hadoop-*-tools.jar:\cygdrive\d\@sze\hadoop\latest\build\hadoop-*-tools.jar
  java.lang.NoClassDefFoundError: foo
  Exception in thread "main" bash-3.2$
