> Zero length files in container log output haven't got a header
> --------------------------------------------------------------
>
> Key: YARN-9808
> URL: https://issues.apache.org/jira/browse/YARN-9808
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: log-aggregation, yarn
> Affects Versions: 3.2.0
> Reporter: Adam Antal
> Assignee: Adam Antal
> Priority: Major
> Attachments: YARN-9808.001.patch
>
>
> Using the Yarn logs CLI for containers that have zero length files produces output similar to this:
> {noformat}
> End of LogType:stderr
> ***********************************************************************
> End of LogType:prelaunch.err
> ******************************************************************************
> Container: container_e25_1567431105510_0001_01_000002 on host-1
> LogAggregationType: AGGREGATED
> =======================================================================================================
> LogType:container.log
> LogLastModifiedTime:Mon Sep 02 06:34:48 -0700 2019
> LogLength:5442
> LogContents:
> ...
> ...
> {noformat}
> Note that stderr and prelaunch.err are both zero length files. Though the output is not misleading, the header is missing.
> I suggest to add the header for zero length files as well, primarily for the following reasons:
> - for applications having multiple files with the same name you may want to distinguish them by host - if many of those are of zero length, you can not extract this information from here. Note that this is a common case for stderr and prelaunch.err.
> - you may want to see the modification time (which corresponds to the creation time of the zero length file)
> - would explicitly display the "LogLength:0" line, which would avoid any confusion from end user side.
