Andrew Wang commented on HDFS-6546: ----------------------------------- We had a request from Hive for this feature. For a table in an encryption zone, they want to put intermediate output inside a per-zone tmp dir, rather than /tmp. The easiest way for them to do this is being able to query the EZ for a table. > 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 > Reporter: Charles Lamb > Assignee: Charles Lamb > > 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 -- This message was sent by Atlassian JIRA (v6.2#6252)
