OS:-ubuntu
ram:-16gb
Storage:-500GB
CPU:-i5 10th gen
i have Cloned ES in two different directory :
Es1
Es2
Then first i launched Es1/bin/elastisearch
And next i launched Es2/bin/elastisearch
while Es2 is launching it immediately killed the es1 process
again i try to run Es1 , Now it killed Es2 process
I even changed my port numbers
Please help me out with this 
Please don't post images of text as they are hard to read, may not display correctly for everyone, and are not searchable.
Instead, paste the text and format it with </> icon or pairs of triple backticks (```), and check the preview window to make sure it's properly formatted before posting it. This makes it more likely that your question will receive a useful answer.
It would be great if you could update your post to solve this.
I saw that you removed the images but you are not providing the logs.
Could you provide the logs please?

these are the ES2 logs
so When i run ES2 its killing the process of ES1
i have changed the port too
What does the config files look like?
# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.

this is ES1
please anyone guide me through fixing this
What's most likely happening here is that the second node is being killed by the system OOM killer. By default Elasticsearch automatically determines appropriate JVM heap size based on total system memory. Part of this heuristic is the assumption that only one Elasticsearch node will be running on the system at a time. We can see from the reported JVM argument -Xms7887m that Elasticsearch is using nearly 8GB of heap so with two nodes running we quickly exhaust the total system memory of 16GB. I'd suggest you manually configure each node's heap to ensure you stay within system limits.
thanks alot it helped me . 
Omg so that explains a lot!
I was trying to run a demo with multiple nodes locally, using the data.path option as always:
# Terminal 1
./bin/elasticsearch
# Terminal 2
./bin/elasticsearch -Epath.data=/tmp/esbis
This was working fine on other 7.x versions (at least on 7.5). But on 7.13, running the second node was always killing the first one, with no log / no explanation.
The reason being that the default HEAP setting has been changed from 1 Gb to half the available memory by default (Autodetermine heap settings based on node roles and total system memory by mark-vieira · Pull Request #65905 · elastic/elasticsearch · GitHub).
The solution is to force a lower HEAP:
ES_JAVA_OPTS="-Xms1g -Xmx1g" ./bin/elasticsearch
Thanks for the solution - still not sure why my main node is getting killed when trying to start a second one tho, I would have expected the second one to just refuse starting by lack of available HEAP, not kill and replace the existing node ^^
