Review Comment:
I think initially we went with that, but then changed it to be an alone
audit log tool, not quite sure why we didn't go that route. Were there any
plans to remove s3guard tool in the future, since we would have to separate it
out then.
> Analyzing S3A Audit Logs
> -------------------------
>
> Key: HADOOP-18257
> URL: https://issues.apache.org/jira/browse/HADOOP-18257
> Project: Hadoop Common
> Issue Type: Task
> Components: fs/s3
> Reporter: Sravani Gadey
> Assignee: Mehakmeet Singh
> Priority: Major
> Labels: pull-request-available
>
> The main aim is to analyze S3A Audit logs to give better insights in Hive and
> Spark jobs.
> Steps involved are:
> * Merging audit log files containing huge number of audit logs collected
> from a job containing various S3 requests.
> * Parsing audit logs using regular expressions i.e., dividing them into key
> value pairs.
> * Converting the key value pairs into CSV file and AVRO file formats.
> * Querying on data which would give better insights for different jobs.
> * Visualizing the audit logs on Zeppelin or Jupyter notebook with graphs.
