Subject [jira] [Updated] (SPARK-18974) FileInputDStream could not detected files which moved to the directory
Date Fri, 30 Dec 2016 03:09:58 GMT

     [ https://issues.apache.org/jira/browse/SPARK-18974?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Adam Wang updated SPARK-18974:
------------------------------
    Description: FileInputDStream use mod time to find new files, but if a file was moved
into the directories it's modification time would not be changed, so FileInputDStream could
not detect these files.  (was: FileInputDStream use mod time to find new files, but if a file
was moved into the directories it's modification time would not be changed, so FileInputDStream
could not detect these files.

I think a way to fix this bug is get access_time and do judgment, bug it need a Set of files
to save all old files, it would very inefficient for lot of files directory.)
