   @sodonnel  Thank you for telling this. In fact i used to use HADOOP_OPTS and HADOOP_CLIENT_OPTS to achieve my debug purpose, but it hard to support me to write the following script.
   
   ```bash
   bin/ozone scm --init
   bin/ozone --daemon start scm
   sh /Users/mbl/projects/github/hadoop-ozone/.project/hadoop/copyconfig.sh om
   bin/ozone om --init
   bin/ozone --daemon start om
   bin/ozone --daemon start recon
   bin/ozone sh vol create myvol;  bin/ozone sh bucket create myvol/mybucket
   bin/ozone --daemon start datanode
   
   ```
   
   I want to start the debug agent of each ozone server with different port. If we have this PR, we can 
   ```bash
   
   bin/ozone scm --init
   bin/ozone --jvmargs " -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5000" --daemon start scm
   bin/ozone om --init
   bin/ozone --jvmargs " -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5001"  --daemon start om
   bin/ozone --jvmargs " -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5002"  --daemon start recon
   bin/ozone sh vol create myvol;  bin/ozone sh bucket create myvol/mybucket
   bin/ozone --jvmargs " -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5003"  --daemon start datanode
   ```
