Disabling S3Guard and destroying a table

To disable S3Guard, you must delete the per-bucket fs.s3a.metadatastore.impl parameter or set it back to the default org.apache.hadoop.fs.s3a.s3guard.NullMetadataStore.

If you are not using a shared table, in DynamoDB console on AWS, delete the DynamoDB table to avoid incurring unnecessary costs.

Destroying S3Guard table

The command hadoop s3guard destroy can be used on the command line to destroy a table.

hadoop s3guard destroy s3a://guarded-table/

          Metadata store DynamoDBMetadataStore{region=eu-west-1, tableName=guarded-table} is initialized.

Metadata store is deleted.

Destroying a table does not destroy the data in S3; it merely removes the summary data used by S3Guard to provide consistent listings. You can verify this by listing the bucket:

> hadoop fs -ls -R  s3a://guarded-table/
-rw-rw-rw-   1 alice alice          0 2019-07-31 20:45 s3a://guarded-table/example
