-----------------------------------
Summary: S3Guard fsck: Detect if a directory if authoritative and
highlight errors if detected in it
Key: HADOOP-16563
URL: https://issues.apache.org/jira/browse/HADOOP-16563
Project: Hadoop Common
Issue Type: Sub-task
Reporter: Gabor Bota
Followup from HADOOP-16423.
One of the changes with the HADOOP-16430 PR is that we now have an S3A FS
method boolean allowAuthoritative(final Path path) that takes a path and
returns true iff its authoritative either by the MS being auth or the given
path being marked as one of the authoritative dirs. I think the validation when
an authoritative directory is consistent between the metastore and S3 should be
using this when it wants to highlight an authoritative path is inconsistent.
This can be a follow-on patch, because as usual it will need more tests, in the
code, and someone to try out the command line.
