[jira] [Comment Edited] (FLINK-23564) Make taskmanager.out and
taskmanager.err rollable
[ https://issues.apache.org/jira/browse/FLINK-23564?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17393778#comment-17393778 ]

---------------------------------------------------------------
[~wangyang0918] Maybe using log4j2-iostreams is an alternative choice to implemention, but it doesn't flush the buffer and would cause OutOfMemory error when using print, println didn't have this problem. I can't solve it and my implemention is mostly like yours. So far I didn't find any problem what other devs are concerned about.

> Now users can use System.out.print/System.out.println/System.err.print/System.err.println/e.printStackTrace to taskmanager.out and taskmanager.err as much as they want and this may use large space of disk cause the disk problem and influence the checkpoint of the flink and even the stability of the flink or other application on the same node. I proposed that we can make the taskmanager.out and taskmanager.err rollable just like taskmanager.log.By doing this, the disk consume of the taskmanager.out and taskmanager.err can be control.
