Subject [jira] [Commented] (HADOOP-14973) [s3a] Log StorageStatistics
Date Fri, 27 Oct 2017 17:27:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14973?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16222715#comment-16222715

Sean Mackrory commented on HADOOP-14973:

I think you misunderstand where these requests are coming from, because it's not coming from
my employer's customers. Doing my best to approach this wearing my "Apache Hat" - I would
appreciate it if you extended the same courtesy.

> S3A is currently storing much more detailed metrics via StorageStatistics than are logged
in a MapReduce job. Eventually, it would be nice to get Spark, MapReduce and other workloads
to retrieve and store these metrics, but it may be some time before they all do that. I'd
like to consider having S3A publish the metrics itself in some form. This is tricky, as S3A
has no daemon but lives inside various other processes.
> Perhaps writing to a log file at some configurable interval and on close() would be the
best we could do. Other ideas would be welcome.
