Heap space in Java is used for dynamic memory allocation for Java objects and JRE classes at the runtime. New objects are always created in heap space and the references to this objects are stored in stack memory.
heap space are configured via** -Xms and -Xmx in mbs**
sudo nano /etc/elasticsearch/jvm.options
Modify the value of -Xms and -Xmx
Best practise , dont put more that 45% of your RAM
Xms represents the initial heap space
Xmx represents the maximum heap space
in case of 1GB let it be
-Xms256m -Xmx256m
Now restart Elastic Search
sudo systemctl restart elasticsearch
