[jira] [Created] (HADOOP-17470) Collect more S3A IOStatistics

Steve Loughran created HADOOP-17470:
---------------------------------------

             Summary: Collect more S3A IOStatistics
                 Key: HADOOP-17470
                 URL: https://issues.apache.org/jira/browse/HADOOP-17470
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
            Reporter: Steve Loughran


collect more stats of 
* how long FS API calls are taking
* what is going wrong

API
* Duration of rename(), delete() other common API Calls.
* openFile: how long the open operation is taking, split of open and openfile
* time to initialize FS instance (maybe better in FileSystem.cache?)
* create: Time to complete the create checks
* finishedWrite: time to execute finishedWrite operations (which may include bulk deletes)

Failure tracking: what failures are we seeing as counters
Interrupts, connections, auth failures:

This would be done in S3ARetryPolicy with an IOStatisticsStore passed in.
