Work on HDFS-6546 started by Charles Lamb.
> Add non-superuser capability to get the encryption zone for a specific path
> ---------------------------------------------------------------------------
>
> Key: HDFS-6546
> URL: https://issues.apache.org/jira/browse/HDFS-6546
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: namenode, security
> Affects Versions: fs-encryption (HADOOP-10150 and HDFS-6134)
> Reporter: Charles Lamb
> Assignee: Charles Lamb
> Attachments: HDFS-6546.001.patch

>
> Need to add protocol, api, and CLI that allows a non super user to ask
> whether a path is part of an EZ, and if so, which one.
> FileStatus should have a 'boolean isEncrypted()' method. (it was in the
> context of discussing with AndreW about FileStatus being a Writable).
> Having this method would allow MR JobSubmitter do the following:
> -----
> BOOLEAN intermediateEncryption = false
> IF jobconf.contains("mr.intermidate.encryption") THEN
> intermediateEncryption = jobConf.getBoolean("mr.intermidate.encryption")
> ELSE
> IF (I/O)Format INSTANCEOF File(I/O)Format THEN
> intermediateEncryption = ANY File(I/O)Format HAS a Path with status
> isEncrypted()==TRUE
> FI
> jobConf.setBoolean("mr.intermidate.encryption", intermediateEncryption)
> FI
