Subject [jira] [Commented] (HDFS-10756) Expose getTrashRoot to HTTPFS and WebHDFS
Date Wed, 02 Nov 2016 16:42:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10756?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15629530#comment-15629530

Xiao Chen commented on HDFS-10756:

Thanks Yuanbo, patch 7 LGTM. Won't fix the checkstyles to keep consistency with current code
base. The test failure seems unrelated, and created HDFS-11093 for that.

Will wait until Friday to commit, in case [~jojochuang], [~andrew.wang] or other watchers
have comments.

bq. If you don't mind, I will take HDFS-11091 over to see what I can do.
Sure, thanks for asking.

> Currently, hadoop FileSystem API has [getTrashRoot|https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileSystem.java#L2708]
to determine trash directory at run time. Default trash dir is under {{/user/$USER}}
> For an encrypted file, since moving files between/in/out of EZs are not allowed, when
an EZ file is deleted via CLI, it calls in to [DFS implementation|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/DistributedFileSystem.java#L2485]
to move the file to a trash directory under the same EZ.
> This works perfectly fine for CLI users or java users who call FileSystem API. But for
users via httpfs/webhdfs, currently there is no way to figure out what the trash root would
be. This jira is proposing we add such interface to httpfs and webhdfs.
