elek opened a new pull request #1232: HDDS-1914. Ozonescript example docker-compose cluster can't be started
URL: https://github.com/apache/hadoop/pull/1232
 
 
   the compose/ozonescripts cluster provides an example environment to test the start-ozone.sh and stop-ozone.sh scripts.
   
   It starts containers with sshd daemon but witout starting the ozone which makes it possible to start those scripts.
   
   Unfortunately the docker files are broken since:
    * we switched from debian to centos with the base image
    * we started to use /etc/hadoop instead of /opt/hadoop/etc/hadoop for configuring the hadoop (workers file should be copied there)
    * we started to use jdk11 to execute ozone (instead of java8)
   
   The configuration files should be updated according to these changes. 
   
   # How to test this patch?
   
   (1) Do a full build and try to start the ./compose/ozonescripts cluster (check the related README file in the directory):
   
   ```
   docker-compose up -d
   ```
   
   (2) start the ozone processes with ./start.sh (from compose/ozonescripts)
   
   (3) wait and check if om/scm webui are working and you have 1 healthy datanode
