Varun Saxena commented on MAPREDUCE-6380:
-----------------------------------------

[~lewuathe], why not simply catch FileNotFoundException in deleteOldLogDirsFrom method ?
We are calling FileSystem#listStatus on the user log directory in this method anyways. 
Is the additional call to FileSystem#listStatusIterator in run() method required ?

> AggregatedLogDeletionService will throw FileNotFoundException when there are some extraneous directories put in remote-log-dir. The deletion function will try to listStatus against the "extraneous-dir + suffix"  dir.  I think it would be better  if  the function can ignore these directories.
