vinoyang commented on FLINK-13987:
----------------------------------
[~lining] Right, IMO, the existed implementation is not meaningless. It would
be better reuse it(line range) and some exist implementation(for example, our
log file list feature) to promote this big feature fastly. WDYT?

> Key: FLINK-13987
> URL: https://issues.apache.org/jira/browse/FLINK-13987
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / REST
> Reporter: lining
> Priority: Major
>
> As the job running, the log files are becoming large.
> Current log api returns all contents，it will block or not work when file is
> large.It's unfriendly for user.
> As application runs on jvm, sometime user need see log of gc, but there
> aren't this contents.
> Above all, we need new apis:
> * list taskmanager all log file
> ** /taskmanagers/taskmanagerid/logs
> **
> {code:java}
> {
> "logs": [
> {
> "name": "taskmanager.log",
> "size": 12529
> }
> ]
> } {code}
> * see taskmanager log file by range
> ** /taskmanagers/taskmanagerid/logs/:filename?start=[start]&count=[count]
> **
> {code:java}
> {
> "data": "logcontent",
> "file_size": 342882
> }
> {code}
> * list jobmanager all log file
> ** /jobmanager/logs
> **
> {code:java}
> {
> "logs": [
> {
> "name": "jobmanager.log",
> "size": 12529
> }
> ]
> }
> {code}
> * see jobmanager log file by range
> ** /jobmanager/logs/:filename?start=[start]&count=[count]
> **
> {code:java}
> {
> "data": "logcontent",
> "file_size": 342882
> }
