[jira] [Commented] (HADOOP-15982) Support configurable trash
location
[ https://issues.apache.org/jira/browse/HADOOP-15982?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16710877#comment-16710877 ]
Wei-Chiu Chuang commented on HADOOP-15982:
------------------------------------------
Basically the use case is: the cluster has application data and user data. When a user deletes application data, we want the data moved into a separate trash directory the space is not limited by the user's quota.

> Key: HADOOP-15982
> URL: https://issues.apache.org/jira/browse/HADOOP-15982
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs
> Affects Versions: 3.0.0
> Reporter: George Huang
> Assignee: George Huang
> Priority: Minor
>
> Currently some customer has users accounts that are functional ids (fid) to manage application and application data under the path /data/FID. These fid's also get a home directory under /user path. The user's home directories are limited with space quota 60 G. When these fids delete data, due to customer deletion policy they are placed in /user/<FID>/.Trash location and run over quota.
> For now they are increasing quotas for these functional users, but considering growing applications they would like the .Trash location to be configurable or something like /trash/\{userid} that is owned by the user.
> What should the configurable path look like to make this happen? For example, some thoughts may relate whether we want to configure it for per user or per cluster, etc.
> Here is current behavior:
> fs.TrashPolicyDefault: Moved: 'hdfs://ns1/user/hdfs/test/1.txt to trash at: hdfs://ns1/user/hdfs/.Trash/Current/user/hdfs/test/1.txt
> for path under encryption zone:
> fs.TrashPolicyDefault: Moved: 'hdfs://ns1/scale/2.txt' to trash at hdfs://ns1/scale/.Trash/hdfs/Current/scale/2.txt
