Xintong Song created FLINK-17677:
------------------------------------
Summary: FLINK_LOG_PREFIX recommended in docs is not always
available
Key: FLINK-17677
URL: https://issues.apache.org/jira/browse/FLINK-17677
Project: Flink
Issue Type: Bug
Components: Documentation
Affects Versions: 1.10.1, 1.9.3, 1.11.0
Reporter: Xintong Song
Fix For: 1.11.0, 1.10.2, 1.9.4
The [Application Profiling &
Debugging|https://ci.apache.org/projects/flink/flink-docs-master/monitoring/application_profiling.html]
documentation recommend to use the script variable {{FLINK_LOG_PREFIX}} for
defining log file paths. However, this variable is only available in standalone
mode. This is a bit misleading for users of other deployments (see this
[thread|http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Flink-Memory-analyze-on-AWS-EMR-td35036.html]).
I propose to replace {{FLINK_LOG_PREFIX}} with a general representation
{{<your-log-path>}}, and add a separate section to discuss how to set the log
path (e.g., use {{FLINK_LOG_PREFIX}} with standalone deployments and
{{<LOG_DIR>}} with Yarn deployments).
