Description
Now that upstream has accepted quite a few of our JIRAs we can get rid of some of the workaround we used to have in Hadoop packaging. This include:
- bigtop-jsvc linking
- bigtop-tomcat linking
- hadoop artifcats being down in lib
- httpfs requiring its own libexec subdir
Also, while we're at it we might as well tidy up the following:
- make hadoop-layout.sh define the complete layout including the HOME_* dirs but it such a way that it can be overriden
- add missing HADOOP_SECURE_DN_PID_DIR & HADOOP_SECURE_DN_LOG_DIR
- remove an extraneous start() function definition from the init.d.tmpl (don't even know how it ended up there)
