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
