There is insufficient memory for the Java Runtime Environment to continue hbase

I have gone through all the answers related to similar questions, but I was unable to come to a conclusion about the issue being in my Java code or Hbase configuration. So I am posting this question again. I am getting bellow error in Hbase. I have 3 VMs for Hadoop cluster.

Master node - 3 GB RAM

Datanode 1 - 7 GB RAM

Datanode 2 - 7 GB RAM

My Java program is running on Hbase Master Node, this worker insert data into the Hbase table and approximately after inserting 100k records I got below error and both the Java program and HMaster stopped working.

Java Program Error :-

OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00007fe05185c000, 12288, 0) failed; error='Cannot allocate memory' (errno=12)

There is insufficient memory for the Java Runtime Environment to continue. Native memory allocation (malloc) failed to allocate 12288 bytes for committing reserved memory.

An error report file with more information is saved as:

You have almost no free memory and no swap.

physical 3523172k(135048k free), swap 0k(0k free)

The simplest solution is to add some swap space, I suggest 4 GB minimum, up to 16 GB.
