Manuel Lagang created GIRAPH-761:
------------------------------------
Summary: GiraphFileInputFormat ignores hidden file filter in
folders
Key: GIRAPH-761
URL: https://issues.apache.org/jira/browse/GIRAPH-761
Project: Giraph
Issue Type: Bug
Components: graph
Affects Versions: 1.1.0
Reporter: Manuel Lagang
Priority: Minor
Fix For: 1.1.0
If a folder is given as an input path to GiraphFileInputFormat, the default
hidden file filter is not applied to the files in the folder. That is, hidden
files (e.g. files preceded by underscores) that would not normally be handled
if targeted directly are unexpectedly being passed as input if the parent
folder is passed instead.
I would expect that when a folder is specified as input, only *non-hidden*
files in that folder will be processed. This is consistent with the base hadoop
FileInputFormat.
