Steve Loughran updated HADOOP-13786:
------------------------------------
Attachment: HADOOP-13786-HADOOP-13345-023.patch
Patch 23
Work done while mostly offline/travelling, so more housekeeping than featur.
People on conference wifi get upset if you do s3 scale tests.
* Unified constants across committer and with S3 core (e.g. same partition
sized used for staging committer part uploads as block output)
* made all the import structures consistent
* WiP on documenting config options.
* Magic committer's abort outcomes more explicit by moving to enum of outcomes
rather than a simple success/fail, adding ABORTED and ABORT_FAILED to achieve
this.
Test changes primarily related to intermittent test failures; one problem was
that if >1 committer test ran in parallel, they could interfere. The Fork ID is
now used for the Job ID. That is trickier than you'd think, hence changes to
the hadoop-aws POM.
Next todo items
* Rebase onto latest HADOOP-13345 ( after that catches up with trunk again)
* Move staging onto s3a FS methods
* instrument committer operations (maybe add counters for the committers? Or
just have them access some new FS stats, "pending commits", "completed"...
> Add S3Guard committer for zero-rename commits to consistent S3 endpoints

> A goal of this code is "support O(1) commits to S3 repositories in the
> presence of failures". Implement it, including whatever is needed to
> demonstrate the correctness of the algorithm. (that is, assuming that s3guard
> provides a consistent view of the presence/absence of blobs, show that we can
> commit directly).
> I consider ourselves free to expose the blobstore-ness of the s3 output
> streams (ie. not visible until the close()), if we need to use that to allow
> us to abort commit operations.
