Re: error copying file from local to hadoop fs

Hello,
In the Safe Mode, -copyFromLocal would not work.
Please read:
http://hadoop.apache.org/docs/stable/hdfs_user_guide.html#Safemode

Please wait a bit for the HDFS system to exit SafeMode. If it takes a
significantly long time, and the HDFS is still in the SafeMode, something
could be wrong with your HDFS setup.
