can we change the path of java installed folder?how?

Question

I am learning Hadoop. On my windows system java is installed at C:/Program files/Java , but the problem is, I believe the white space in program files.

After setting all hadoop configuration files, When I run the command namenode format it give the following error.

$ bin/hadoop namenode -format bin/hadoop: line 350: C:\Program
Files\Java\jdk1.7.0_71/bin/java: No such file or directory

So is there any way by which i can change the java folder location to C:/Java from C:/Program files/Java

Thanks.

Answer 1

copy pasting the java folder to C:/Java from C:/Program files/Java and updating the environment variables with new path worked for me

Answer 2

If you do not want to move your java installation, you can try following possibilities:

1. set your java path within quotation
2. use the ~ operand -> your path is then C:\Program~1\Java\jdk1.7.0_71
