[jira] [Updated] (ATLAS-3610) [ARCHIVED] Unify logging logic by
relying solely on log4j configuration for java processes
[ https://issues.apache.org/jira/browse/ATLAS-3610?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mariusz Górski updated ATLAS-3610:
----------------------------------
Component/s: (was: atlas-core)
Fix Version/s: (was: 3.0.0)
Affects Version/s: (was: 3.0.0)
Description: (was: *Problem description*
When starting Atlas, Python scripts are invoked to spawn all necessary processes. This is achieved with the use of _subprocess.Popen()_ in _runProcess()_ function of _atlas_config.py_ script. While doing that, stdout is being redirected to log files, which (for java processes) can override log4j configuration (if configured with stdout handler). This creates situation when log4j configuration cannot be relied upon and prevents logging to stdout.
*Proposed solution*
* Add possibility to unify logging logic by relying solely on log4j configuration.
* Adjust _runProcess()_ function from _atlas_config.py_ script (and all functions relying on it) not to redirect stdout and stderr of spawned processes when logdir is _None_
* Add _RELY_ON_LOG4J_ONLY_ env variable (defaulting to False) for backwards compatibility.
*Predicted Benefits*
This improvement would bring the benefit of having single place where logging logic is defined (log4j config file) and enable logging to stdout, which could be very useful when running Atlas in docker container or in Kubernetes/OC, where some logging scraping is present.)
