-----------------------------
Resolution: Duplicate
> yarn logs can get corrupted if the aggregator does not have permissions to
> the log file it tries to read
> --------------------------------------------------------------------------------------------------------
>
> Key: YARN-2240
> URL: https://issues.apache.org/jira/browse/YARN-2240
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 2.5.0
> Reporter: Mit Desai
>
> When the log aggregator is aggregating the logs, it writes the file length
> first. Then tries to open the log file and if it does not have permission to
> do that, it ends up just writing an error message to the aggregated logs.
> The mismatch between the file length and the actual length here makes the
> aggregated logs corrupted.
