> CallerContext to set Hadoop cloud client audit context
> ------------------------------------------------------
>
> Key: SPARK-51072
> URL: https://issues.apache.org/jira/browse/SPARK-51072
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Affects Versions: 4.1.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Minor
> Labels: pull-request-available
> Fix For: 4.1.0
>
>
> CallerContext adds information about the spark task to hadoop IPC context and
> then to HDFS, YARN and HBase server logs.
> It is also possible to update the cloud storage "audit context".
> Storage clients can attach the audit information to requests to be stored in
> the service's own logs, where it can be retrieved, parsed and used for
> analysis.
> It is currently supported by the S3A connector, which adds the information to
> a synthetic referrer header, which is then stored in the S3 Server logs. (Not
> cloudtrail, sadly).
> See
> https://hadoop.apache.org/docs/current/hadoop-aws/tools/hadoop-aws/auditing.html
> CallerContext can be enhanced to attach the generated {{context}} string to
> the audit context, so it will propagate to the logs.
