Subject [jira] [Commented] (HDFS-8831) Trash Support for deletion in HDFS encryption zone
Date Fri, 04 Dec 2015 18:33:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8831?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15041935#comment-15041935

Xiaoyu Yao commented on HDFS-8831:
----------------------------------

The recent Jenkins shows failure in these related tests. The first one can not repro on my
local machine. The second test does not exist. 
{code}
 org.apache.hadoop.hdfs.TestEncryptionZones.testEncryptionZoneWithTrash
 org.apache.hadoop.hdfs.TestEncryptionZonesWithKMS.testEncryptionZoneWithTrash
{code}

The mvninstall issue seems to infra issue unrelated to this change. I will commit the patch
shortly.

> Currently, "Soft Delete" is only supported if the whole encryption zone is deleted. If
you delete files whinin the zone with trash feature enabled, you will get error similar to
the following 
> {code}
> rm: Failed to move to trash: hdfs://HW11217.local:9000/z1_1/startnn.sh: /z1_1/startnn.sh
can't be moved from an encryption zone.
> {code}
> With HDFS-8830, we can support "Soft Delete" by adding the .Trash folder of the file
being deleted appropriately to the same encryption zone.
