---------------------------------
Summary: FileInputDStream could not detected files which moved to
the directory
Key: SPARK-18974
URL: https://issues.apache.org/jira/browse/SPARK-18974
Project: Spark
Issue Type: Bug
Components: DStreams, Input/Output
Affects Versions: 2.0.2, 1.6.3
Reporter: Adam Wang
FileInputDStream use mod time to find new files, but if a file was moved into
the directories it's modification time would not changed, so FileInputDStream
could not detected 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.
