Worklog Id: (was: 535449)
Time Spent: 10h 10m (was: 10h)
> Add Public IOStatistics API
> ---------------------------
>
> Key: HADOOP-16830
> URL: https://issues.apache.org/jira/browse/HADOOP-16830
> Project: Hadoop Common
> Issue Type: New Feature
> Components: fs, fs/s3
> Affects Versions: 3.3.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10h 10m
> Remaining Estimate: 0h
>
> Applications like to collect the statistics which specific operations take,
> by collecting exactly those operations done during the execution of FS API
> calls by their individual worker threads, and returning these to their job
> driver
> * S3A has a statistics API for some streams, but it's a non-standard one;
> Impala &c can't use it
> * FileSystem storage statistics are public, but as they aren't cross-thread,
> they don't aggregate properly
> Proposed
> # A new IOStatistics interface to serve up statistics
> # S3A to implement
> # other stores to follow
> # Pass-through from the usual wrapper classes (FS data input/output streams)
> It's hard to think about how best to offer an API for operation context
> stats, and how to actually implement.
> ThreadLocal isn't enough because the helper threads need to update on the
> thread local value of the instigator
> My Initial PoC doesn't address that issue, but it shows what I'm thinking of
