I'm new and learning to start a hadoop system using Docker but I have been stuck at one point for weeks and finally I have to ask here. I could launch the containers individually without any problems and the namenode always recognized the running namenodes. However, when I tried to set up a Docker-compose.yml file to launch all containers at once, I got into multiple problems, one of which is that the namenode never recognized the running datanodes. Do you have any suggestions to help me fix it?
Here's my docker-compose file:

I want to deploy a service that will allow me to use Spark and MongoDB in a Jupiter notebook.
I use docker-compose to build up the service, and it`s as followed:
version: "3.3"
volumes:
shared-workspace:
networks:
spark-net:
driver: bridge
services:
spark-master:
image: uqteaching/cloudcomputing:spark-master-v1
container_name: spark-master
networks:

ports:

- "7077:7077"
environment:
- INIT_DAEMON_STEP=setup_spark

- "PYSPARK_DRIVER_PYTHON=/usr/bin/python3"
spark-worker-1:
image: uqteaching/cloudcomputing:spark-worker-v1
container_name: spark-worker-1
depends_on:
- spark-master
networks:

ports:

environment:

spark-worker-2:

depends_on:

environment:

depends_on:

--ip=0.0.0.0 \
--allow-root \
--no-browser \
--notebook-dir=/home/jovyan/work/nbs \
--NotebookApp.token='' \
--NotebookApp.password=''
"
And the result is something like this:
I dont know why. Even I set these 2` services to listen to a different port.
They are using 8081/tcp at the same time, which caused them both to crash.
I want to solve this.
mongo-express seems to need port 8081 internal, so use another external port to be able to login to the webui.
http://localhost:8092 would then be something like this:
mongo_admin:
image: mongo-express
container_name: 'mongoadmin'
networks:
- "spark-net"
depends_on:
- mongo
links:
- mongo
ports:
- "8092:8091"
May be somebody had such specific problem... There are two web applications in different directories, both in docker containers. Linux (centos). When I run the first application (docker-compose up -d) everything works fine. If I launch the second application from another directory, then the first one docker container launched falls. Why? The names of the containers are different, the ports forwarded in the docker are also different.
First app config docker-compose.yml

I have an Hadoop cluster with one namenode and one datanode instantiated with docker compose. In addition I am trying to launch Hive but the Hive-metastore seems not to find my datanode even if this one is up and running, infact checking the log it shows:
namenode:9870 is available.
check for datanode:9871...
datanode:9871 is not available yet
try in 5s once again ...

but here spark worker is not connected to spark master getting exceptions, here is exception log details , can some one please guide me why am facing this issue
Note : I am trying to create these services in drone.yml for my integration testing
Answering for better formatting. The comments suggest sleeping. Assuming this is the dockerfile (https://hub.docker.com/r/bde2020/spark-worker/dockerfile) You could sleep by adding the command:
spark-worker-1:
image: bde2020/spark-worker:2.4.4-hadoop2.7
container_name: spark-worker-1
command: sleep 10 && /bin/bash /worker.sh
depends_on:
- spark-master
ports:
- "8081:8081"
environment:
- "SPARK_MASTER=spark://spark-master:7077"
Although sleep 10 is probably excessive, if this would would sleep 5 or sleep 2

When I run docker-compose build and docker-compose up, I get "unable to revive connection: http://elasticsearch:9200" from every container. I don't think any of the containers are able to talk to each other right now. However, it really feels like everything should work because I have exposed all the ports for elastic components, linked them with same networks and URL is also pointing to the correct alias. What am I doing wrong?
The dockerfile settings are all correct as each container runs correctly in isolation - just not able to talk to each other at all
