Aljoscha Krettek commented on FLINK-16809:
------------------------------------------
I believe {{CallerContext}} is a Hadoop concept that allows figuring out from
what application/deployment interaction with a Hadoop/HDFS is coming from.
> Support setting CallerContext on YARN deployments

> Project: Flink
> Issue Type: Improvement
> Components: Deployment / YARN
> Reporter: zhuqi
> Priority: Major
>
> Now the Spark and hive have the Call Context to meet the HDFS Job Audit
> requirement.
> I think the flink also should to add it, and in our cluster the flink job may
> have big pressure to the HDFS, it's will be helpful to find the root job.
