Subject [jira] [Commented] (HADOOP-13650) S3Guard: Provide command line tools to manipulate metadata store.
Date Fri, 11 Nov 2016 02:09:58 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13650?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15655862#comment-15655862
] 

Mingliang Liu commented on HADOOP-13650:
----------------------------------------

See {{DynamoDBMetadataStore#initialize(Configuration conf)}} in v3+ patch in [HADOOP-13449].
I hope this will help other tools (e.g. command line) that operate the metadata store without
initializing an S3FileSystem, which will check the bucket is there, unnecessarily.

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. 
> http://docs.aws.amazon.com//ElasticMapReduce/latest/ReleaseGuide/emrfs-cli-reference.html
> S3Guard should offer similar functionality.
