Daniel Dai commented on PIG-950:
--------------------------------
I tried, actually Hadoop will ignore files start with "." while processing a
map-reduce job. So guess we can do nothing, just not name the file starts with
".".
> Pig Loader does not handle unix hidden files ( files starting with dot)
