I tried to add HAMA_OPT in hama-env.sh but I get the same error. I did the following steps 1- Stopped Hama 2- Stopped Hadoop 3- Modified the file 4- Started Hadoop 5- Started Hama 6- Ran the ./bin/hama jar command
*Content of hama-env.sh* # The java implementation to use. Required. export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/ export HAMA_OPTS="-Djava.library.path=/home/behroz/Documents/cplex_setup/cplex/bin/x86-64_linux" On Sat, Jun 20, 2015 at 4:25 AM, Edward J.
