Yangze Guo updated FLINK-16548:
-------------------------------
Summary: Expose consistent environment variable to identify the component
name and resource id of jm/tm (was: [Requirement] Consistent id to identify
jm/tm in different cluster modes)

> Key: FLINK-16548
> URL: https://issues.apache.org/jira/browse/FLINK-16548
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Configuration
> Reporter: hejianchao
> Priority: Major
>
> Imagine that there is now s3-log-appender.jar, and logs can be written to s3
> with proper configuration.
> Then, in the same flink job, the exact same log4j configuration is used. How
> to make the key written to s3 for different jm / tm carry the id that
> uniquely identifies jm / tm? such as:
> s3://bucket/flink-logs/jobId/${jm-id}/logfile
> s3://bucket/flink-logs/jobId/${tm-1-id}/logfile
> s3://bucket/flink-logs/jobId/${tm-2-id}/logfile
> For the s3-log-appender here, it needs a way to sense the value of
> ${jm-id}/${tm-1-id}/${tm-2-id}, and it has the following claims :
> 1. This value can be used to locate the actual running jm, tm
> 2. The value is independent of cluster mode, whether standalone, yarn or
> kubernetes
