Disabling S3Guard and Destroying a S3Guard Database

If you decide to disable S3Guard:

  1. From the Ambari web UI, delete the per-bucket fs.s3a.metadatastore.impl parameter or set it back to the default "org.apache.hadoop.fs.s3a.s3guard.NullMetadataStore".

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

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

hadoop s3guard destroy s3a://guarded-table/

2018-05-31 15:35:39,075 [main] INFO  s3guard.S3GuardTool ( -
          Metadata store DynamoDBMetadataStore{region=eu-west-1, tableName=guarded-table} is initialized.
2018-05-31 15:35:39,077 [main] INFO  s3guard.DynamoDBMetadataStore ( -
          Deleting DynamoDB table guarded-table in region eu-west-1
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.
