---------------------------------------

             Summary: Handle FNFE from S3Guard.getMetadataStore() in S3A initialize()
                 Key: HADOOP-15210
                 URL: https://issues.apache.org/jira/browse/HADOOP-15210
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 3.0.0
            Reporter: Steve Loughran


{{S3Guard.getMetadataStore()}} throws FileNotFoundExceptions up, as the comments say " rely
on callers to catch and treat specially"

S3A Filesystem doesn't do that, instead it will just fail FileSystem.initialize; the FNFE
 is generated by DynamoDBMetadataStore.

Are we happy with this? 

Downgrading has some appeal: if you don't have the table, it will keep going. But failures
could be a sign of bad config, so maybe silent recovery is bad.
