> We have around *800 3-5K* files on local file system, we have nfs gateway mounted on
*/hdfs/*, when we tried to copy these files to HDFS by 
> *cp ~/userdata/* /hdfs/user/cqdemo/demo3.data/*
> most of files are failed because of 
> cp: writing `/hdfs/user/cqdemo/demo3.data/TRAFF_201408011220.csv': Input/output error
> cp: writing `/hdfs/user/cqdemo/demo3.data/TRAFF_201408011221.csv': Input/output error
> cp: writing `/hdfs/user/cqdemo/demo3.data/TRAFF_201408011222.csv': Input/output error
> for same set of files, I tried to use hadoop dfs -put command to do the copy, it works
fine.
