             Summary: S3Guard: NPE when table is already populated in dynamodb and user specifies "fs.s3a.s3guard.ddb.table.create=false"
                 Key: HADOOP-13925
                 URL: https://issues.apache.org/jira/browse/HADOOP-13925
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
            Reporter: Rajesh Balamohan
            Priority: Minor


When table is present dynamodb store and already populated, it is possible that users can specify {{fs.s3a.s3guard.ddb.table.create=false}}.  In such cases, {{DynamoDBMetadataStore.get}} would end up throwing NPE as {{table}} object may not be initialized.
