Xiao Chen commented on HDFS-13009:
----------------------------------
Thanks for the discussions guys.
This may come as a side-product of what Andrew asked: it would be good to have
a tool to get more details of an EZ (especially when it's not finalized). We
have getFileEncryptionInfo API to check per-file, but IMO helpful to know about
the status based on entire EZ, and hopefully which files are still unencrypted
so people know what's left to 'finalize' the EZ.
Previously the assumption is if you have an EZ, everything is certainly
encrypted, so motivation for the tool was lesser. :)
> Creation of Encryption zone should succeed even if directory is not empty.

> Key: HDFS-13009
> URL: https://issues.apache.org/jira/browse/HDFS-13009
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: encryption
> Reporter: Rushabh S Shah
> Assignee: Rushabh S Shah
> Priority: Major
>
> Currently we have a restriction that creation of encryption zone can be done
> only on an empty directory.
> This jira is to remove that restriction.
> Motivation:
> New customers who wants to start using Encryption zone can make an existing
> directory encrypted.
> They will be able to read the old data as it is and will be decrypting the
> newly written data.
> Internally we have many customers asking for this feature.
> Currently they have to ask for more space quota, encrypt the old data.
> This will make their life much more easier.
