Clueless re Java: /opt vs. /usr/local
It seems this is a oft debated item, that's over my head.
So here's what I've got:
Java 7 set up at /opt/ but I really want it at /usr/local...
What have I done?
Have: Debian 7 (whezzy) with gnome, so what do I do to set things back where it should be?
I guess this is a hot topic according to these two who made some good points....I'm having issue getting Hadoop happy bc I followed the /opt path for Java and I think /usr/local is what it's looking for...

Think I got it, just needed to set the PATH
Can now run jps

libglpk-java - GNU Linear Programming Kit Java Binding DESCRIPTION
The GNU Linear Programming Kit (GLPK) package supplies a solver for large scale linear programming (LP) and mixed integer programming (MIP). The GLPK project is hosted at http://www.gnu.org/software/glpk. It has two mailing lists: - help-glpk@gnu.org and - bug-glpk@gnu.org. To subscribe to one of these lists, please, send an empty mail with a Subject: header line of just "subscribe" to the list. GLPK provides a library written in C and a standalone solver. The source code provided at ftp://gnu.ftp.org/gnu/glpk/ contains the docu- mentation of the library in file doc/glpk.pdf. The Java platform provides the Java Native Interface (JNI) to integrate non-Java language libraries into Java applications. Project GLPK for Java delivers a Java Binding for GLPK. It is hosted at http://glpk-java.sourceforge.net/. To report problems and suggestions concerning GLPK for Java, please, send an email to the author at xypron.glpk@gmx.de. ARCHITECTURE
A GLPK for Java application will consist of the following - the GLPK library - the GLPK for Java JNI library - the GLPK for Java class library - the application code. GLPK LIBRARY
The GLPK library can be compiled from source code. Follow the instructions in file INSTALL provided in the source distribution. Precompiled packages are available in many Linux distributions. The usual installation path for the library is /usr/local/lib/libglpk.so. The library has to be in the search path for binaries. GLPK FOR JAVA JNI LIBRARY
The GLPK for Java JNI library can be compiled from source code. Follow the instructions in file INSTALL provided in the source distribu- tion. The usual installation path for the library is /usr/local/lib/jni/libglpk-java.so. The library has to be in the search path for binaries. Specify the library path upon invocation of the application, e.g. java -Djava.library.path=/usr/local/libjni GLPK FOR JAVA CLASS LIBRARY
The source code to compile the GLPK for Java class library is provided at http://glpk-java.sourceforge.net. The GLPK for Java class library can be compiled from source code. Follow the instructions in file INSTALL provided in the source distribu- tion. The usual installation path for the library is /usr/local/share/java/glpk-java.jar. The library has to be in the CLASSPATH. Specify the classpath upon invocation of the application, e.g. java -classpath /usr/local/share/java/glpk-java.jar;. SEE ALSO
Further documentation and examples can be found in the documentation path, which defaults to /usr/local/share/doc/libglpk-java. version 1.0.18 September 10th, 2011 libglpk-java(3)
