Error in installation of hadoop 2.8.3 on windows 10 about hadoop-on-window HOT 14 OPEN

I have same problem, but it is solved.

The Problem is, on the file C:\hadoop-3.3.0\etc\hadoop\hadoop-env.cmd.

Edit Last row of the file :

@Rem A string representing this instance of hadoop. %USERNAME% by default.
set HADOOP_IDENT_STRING=%USERNAME%

As default Hadoop will use our username, but some username contain space.
Just Edit %USERNAME% with any word without space.

And put JavaPath in "" inside ,like this.
set JAVA_HOME="C:\Program Files\Java\jdk1.8.0_121"
