Subject [jira] Commented: (HADOOP-4300) When fs.trash.interval is set to non-zero value, the deleted files and directory which are in .Trash are not getting removed from there after <fs.trash.interval>

Ramya R commented on HADOOP-4300:
---------------------------------

Sorry for the mistake Chris. Koji pointed out the right way to execute it. Here is what I
followed:
1)  Allocate a cluster through HOD and pass --gridservice-hdfs.cmdline-params=fs.trash.interval=10
to HOD.
2) Append ><property><name>fs.trash.interval</name> <value>10</value>
<description>Number of minutes between trash checkpoints. If zero, the trash feature
is disabled. </description></property> in hadoop-site.xml under the <cluster_dir>
3) Create some files on HDFS and delete it. 
The files are getting deleted and being moved to .Trash but not being removed from .Trash
after <fs.trash.interval>

Interestingly, I set up a stand alone mode and the files were removed from .Trash after <fs.trash.interval>.
But the same behavior was not seen in distributed mode.

> Set fs.trash.interval to non zero value(say 1), touch a file (say file.txt) and delete
it. The expected behavior would be that file.txt is moved to .Trash and also file.txt is removed
from .Trash after 1min. But the observed behavior is that, even though file.txt is being moved
to .Trash, it is not removed from .Trash after 1min.
