Weiwei Yang updated HDFS-9152:
------------------------------
Description:
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.
