---------------------------------------

             Summary: Preserve logs from BashJavaUtils and make them part of TM logs
                 Key: FLINK-15519
                 URL: https://issues.apache.org/jira/browse/FLINK-15519
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Configuration
    Affects Versions: 1.10.0
            Reporter: Andrey Zagrebin
             Fix For: 1.10.0


In FLINK-13983 we introduced BashJavaUtils utility to call in taskmanager.sh before starting TM and calculate memory configuration for the JVM process of TM.

Ideally, it would be nice to preserve BashJavaUtils logs and make them part of the TM logs. Currently, logging for BashJavaUtils is configured from the class path and can differ from TM logging. Moreover TM logging can rewrite BashJavaUtils even if we align their loggings (e.g. log4j.appender.file.append=false in default log4j.properties  for Flink).
