Steve Loughran commented on HADOOP-16552:
-----------------------------------------
I don't see that much in terms of metric collection in the ABFS connector
-unlike its predecessor.
If you look at org.apache.hadoop.fs.s3a.S3AStorageStatistics you can see how we
can take metrics created in the file system and serve it up the
getStorageStatistics API, where it can be picked up by applications, dumped to
files etc. This might be an opportunity to start working on this feature.
How do you propose to publish information to the store?
