> Ozone serialization codec for Ozone S3 secret table
> ---------------------------------------------------
>                 Key: HDDS-1132
>                 URL: https://issues.apache.org/jira/browse/HDDS-1132
>             Project: Hadoop Distributed Data Store
>          Issue Type: Sub-task
>          Components: Ozone Manager, S3
>            Reporter: Elek, Marton
>            Priority: Major
>              Labels: newbie
> HDDS-748/HDDS-864 introduced an option to use strongly typed metadata tables and separated
the serialization/deserialization logic to separated codec implementation
> HDDS-937 introduced a new S3 secret table which is not codec based.
> I propose to use codecs for this table.
> In OzoneMetadataManager the return value of getS3SecretTable() should be changed from
Table<byte[],byte[]> to Table<S3SecretKey,S3SecretValue>. 
> The encoding/decoding logic of S3SecretValue should be registered in ~OzoneMetadataManagerImpl:L204
> As the codecs are type based we may need a wrapper class to encode the String kerberos
id with md5: class S3SecretKey(String name = kerberodId). Long term we can modify the S3SecretKey
to support multiple keys for the same kerberos id.
