Is the issue here that files in the .Trash are not getting deleted?  But yes, the fs.trash.interval is in the core-site.xml,               fs.trash.interval        360        if you set the value to 0 files should not be moved to .Trash and no cleanup is needed.  [yarn[NAME] conf]$ hadoop fs -rm /user/yarn/test.txt 15/02/10 10:19:53 INFO fs.TrashPolicyDefault: Namenode trash configuration: Deletion interval = 0 minutes, Emptier interval = 0 minutes. Deleted /user/yarn/test.txt  or use the -skipTrash option  Also remember since you can access the Isilon file system outside of HDFS and without hdfs tools, you can delete files using normal methods, these will not be moved to trash either.   russ
ISILON hdfs - fs.trash.interval? How does the trash cleaninig up process work on ISILON HDFS  Does ISILON hdfs has some configuration files of ite own or does it work out of core-site.xml or core-default.xml?  I do not see on ISILON hdfs /user/XYZ/.Trash/Current not getting deleted.  Any insight into this process. Thanks for your help and input. Ashok
