vinoyang commented on FLINK-10306:
----------------------------------
In fact, I think that as the log files are rolled, reading the historical log
file is also a strong demand.
> Support the display of log file from any position on webUI

> Key: FLINK-10306
> URL: https://issues.apache.org/jira/browse/FLINK-10306
> Project: Flink
> Issue Type: Improvement
> Affects Versions: 1.6.0
> Reporter: Jiayi Liao
> Assignee: Jiayi Liao
> Priority: Major
>
> Although we copy the whole log files from taskmanager to blob service host,
> sometimes we may not be able to read the whole file's content on WebUI
> because of the browser's load.
> We already use RandomAccessFile to read files, so I think we need to support
> read the log file from any row of it by adding a parameter at the end of url
> like http://xxx/#/taskmanager/container_xx/log/100.
