Mingliang Liu commented on HADOOP-13650:
----------------------------------------
{quote}
In the current DynamoDBMetadataStore#initialize(Configuration), such case will
raise Exception if we do not explicitly specify s3a URI in the CLI because it
can not create S3AFileSystem.

That's right. For the both options I posted in the parent thread:
https://issues.apache.org/jira/browse/HADOOP-13345?focusedCommentId=15802751&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15802751
we will have to change the DynamoDBMetadataStore accordingly. If you also
prefer the option 2 (both here and parent thread comment) I can prepare a patch
for that. Certainly this can also be addressed later. Thanks!

> Similar systems like EMRFS has the CLI tools to manipulate the metadata
> store, i.e., create or delete metadata store, or {{import}}, {{sync}} the
> file metadata between metadata store and S3.

> S3Guard should offer similar functionality.
