The solution is,

This error is happening because the JVM parameters for the BigDataLite NoSQL has been not set properly. So you need to add the JVM memory paremeters in ~/.bashrc file. follow the steps,
sudo nano ~/.bashrc
Add the below line in to this file,
export JAVA_OPTS="-Xms128m -Xmx2048m -XX:PermSize=256m -XX:MaxPermSize=2048m"
Finally refresh the ~/.bashrc with the below command,
source ~/.bashrc
Now execute it again.
