Hi Team,

I have setup an one node kafka on ec2 free instance which has 8 gb ram and
256 GB hdd. I have installed java 8 on ec2. When I am trying to start kafka
getting error like

OpenJDK 64-Bit Server VM warning: INFO:
os::commit_memory(0x0000000700000000, 1073741824, 0) failed; error='Cannot
allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 1073741824 bytes for
committing reserved memory.
# An error report file with more information is saved as:
# /home/ubuntu/kafka_2.12-2.7.0/hs_err_pid1920.log

I have increased the JAVA_HEAP but nothing happened. How to solve this
problem?

Looking forward to hearing from you.
