Steve Loughran commented on HADOOP-13876:
-----------------------------------------
This will also surface on a {{-Dscale}} test run, as that also hits the public,
read-only landsat dataset.
With HADOOP-13336 you get to control the bucket options individually. For
{{ITestS3AAWSCredentialsProvider}}, it will simply be possible to disable the
metastore for the relevant read-only buckets. All you need to do is set
{{fs.s3a.bucket.landsat-pds.metastore=org.apache.hadoop.fs.s3a.s3guard.NullMetadataStore}}
On that topic, can we support some shorter names for the standard set of
stores, "none", "local", and "dynamo"?
> S3Guard: better support for multi-bucket access including read-only

> Key: HADOOP-13876
> URL: https://issues.apache.org/jira/browse/HADOOP-13876
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: HADOOP-13345
> Reporter: Aaron Fabbri
>
> HADOOP-13449 adds support for DynamoDBMetadataStore.
> The code currently supports two options for choosing DynamoDB table names:
> 1. Use name of each s3 bucket and auto-create a DynamoDB table for each.
> 2. Configure a table name in the {{fs.s3a.s3guard.ddb.table}} parameter.
> One of the issues is with accessing read-only buckets. If a user accesses a
> read-only bucket with credentials that do not have DynamoDB write
> permissions, they will get errors when trying to access the read-only bucket.
> This manifests causes test failures for {{ITestS3AAWSCredentialsProvider}}.
> Goals for this JIRA:
> - Fix {{ITestS3AAWSCredentialsProvider}} in a way that makes sense for the
> real use-case.
> - Allow for a "one DynamoDB table per cluster" configuration with a way to
> chose which credentials are used for DynamoDB.
> - Document limitations etc. in the s3guard.md site doc.
