Sean Mackrory updated HADOOP-13760:
-----------------------------------
Attachment: HADOOP-13760-HADOOP-13345.003.patch
This patch has 2 tests failing without S3Guard that I still need to look into.
Just posting as a sort of checkpoint before the weekend.
I've incorporated all of Fabbri's feedback, and rebased on top of Mingliang's
change to add S3Guard support to listFiles\*. In that change, the behavior
changed to start including intermediate directories, and that did indeed cause
a lot of tests to fail (copyFile failed when attempting to move an empty blob
that didn't exist), so I've implemented a new iterator that only returns leaf
nodes, since that is best for all current uses of listFilesAndDirectories. I
also renamed it to listFilesAndEmptyDirectories to reflect the intention.
> S3Guard: add delete tracking

> Following the S3AFileSystem integration patch in HADOOP-13651, we need to add
> delete tracking.
> Current behavior on delete is to remove the metadata from the MetadataStore.
> To make deletes consistent, we need to add a {{isDeleted}} flag to
> {{PathMetadata}} and check it when returning results from functions like
> {{getFileStatus()}} and {{listStatus()}}. In HADOOP-13651, I added TODO
> comments in most of the places these new conditions are needed. The work
> does not look too bad.
