Siddharth Seth commented on YARN-6509:
--------------------------------------
Is the current proposal to change the default to fetch the last 4K ?
Can we please not make this change. It is definitely incompatible, and I'd
argue that it's not very useful.
The intent of the jira is to protect users against log downloads which could
otherwise take hours and fill up the local fs - apps which generate large logs.
> Add a size threshold beyond which yarn logs will require a force option
