[jira] [Created] (ATLAS-3557) Configurable STDOUT Redirect in Python entrypoint scripts

Mariusz Górski created ATLAS-3557:
-------------------------------------

             Summary: Configurable STDOUT Redirect in Python entrypoint scripts
                 Key: ATLAS-3557
                 URL: https://issues.apache.org/jira/browse/ATLAS-3557
             Project: Atlas
          Issue Type: Improvement
            Reporter: Mariusz Górski


*Background*:

Currently Atlas *entrypoint.sh* uses Python scripts for setup. Executing java process is done through *runProcess* function in *atlas_config.py*, which explicitly redirects *stdout* and *stderr* of those processes to files. We would like this to be configurable, so we are able to use bare log4j config to define our logging strategy. This way logging stream might be easily captured while running Atlas on Docker/Kubernetes, where containers stdout is captured.

 

*Proposal*:

Adding optional *REDIRECT_STDOUT* env variable which defaults to *True* (for backwards compatibility):
 * When *True* - nothing changes
 * When *False* - runProcess is opening subprocess without stdout and stderr kwargs
