--------------------------------
Summary: Enhance TaskManager log visualization by listing all log
files for Flink web UI
Key: FLINK-11782
URL: https://issues.apache.org/jira/browse/FLINK-11782
Project: Flink
Issue Type: Improvement
Components: Runtime / Web Frontend
Reporter: vinoyang
Assignee: vinoyang
Attachments: flink-web-ui-taskmanager-log-files.png,
yarn-container-log-files.png
Currently, there are some features to be enhanced when Flink web UI displays
TaskManager logs:
1) Flink web UI can only display the log of task manager and stdout;
2) Flink web UI can only display the latest one log file;
In the log folder of a Task Manager, we usually have more files, including GC
log files, multiple files generated based on the rolling rules of the logging
framework (time or log file size), user's business log files (We internally
implemented the separation of Flink from the user log). For these files, the
current Flink web UI cannot be displayed.
I personally suggest that we can refer to the way YARN displays the container's
log (see attachment 1), first list all the log files (see attachment 2), and
then click to display the files of these logs.
This feature can be independent or part of the log separation (see FLINK-11202).
