Work Description: steveloughran opened a new pull request #2280:
URL: https://github.com/apache/hadoop/pull/2280
This changes directory tree deletion so that only files are incrementally
deleted
from S3Guard after the objects are deleted; the directories are left alone
until metadataStore.deleteSubtree(path) is invoked
This avoids directory tombstones being added above files/child directories,
which stop that subtree operation from actually finishing.
Also:
* callback to delete objects splits files and dirs so that
any problems deleting the dirs doesn't trigger s3guard updates
* new statistic to measure #of objects deleted, alongside request count.
* callback listFilesAndEmptyDirectories renamed listFilesAndDirectoryMarkers
to clarify behavior.
Test enhancements in ITestDirectoryOperationCost, but I didn't manage to
replicate it there (didn't quite understand the cause); the FileContext
test works for regression testing.
