Solution 3:

Steps:

1. Find your R location. It will be stored in rsession-ld-library-path in rserver.conf file. Or just by doing which R. The location usually is /usr/lib64/R/lib or /usr/lib64/microsoft-r/3.3/lib64/R/lib

2. Find the libjvm.so file which is usually in the usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server path depending on which jre you're using. Check echo $JAVA_HOME.

3. Create a symlink using ln -s sudo ln -s /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server/libjvm.so /usr/lib64/microsoft-r/3.3/lib64/R/lib/libjvm.so

4. Restart R server
