How to move files to hdfs in hadoop using unix command

Question

I have 2 directories "dft" and "hdfs" in the unpacked Hadoop folder. I am trying to copy the file(StartUnit.txt) in dft into hdfs. The corresponding command and exception are as shown below

313159@PC213710 ~/hadoop-0.19.1
$ bin/hadoop dfs -copyFromLocal D:/eclipse/cygwin/home/313159/hadoop-0.19.1/hdfs              
D:/eclipse/cygwin/home/313159/hadoop-0.19.1/dft/StartUnit.txt

HADOOP_NAMENODE_OPTS=-Dcom.sun.management.jmxremote
HADOOP_SECONDARYNAMENODE_OPTS=-Dcom.sun.management.jmxremote
HADOOP_DATANODE_OPTS=-Dcom.sun.management.jmxremote
HADOOP_BALANCER_OPTS=-Dcom.sun.management.jmxremote
HADOOP_JOBTRACKER_OPTS=-Dcom.sun.management.jmxremote
HADOOP_PID_DIR=-Dcom.sun.management.jmxremote
copyFromLocal: Pathname /D:/eclipse/cygwin/home/313159/hadoop-0.19.1/dft/StartUnit.txt 
    from D:/eclipse/cygwin/home/313159/hadoop-0.19.1/dft/StartUnit.txt is not a  
valid DFS filename.
Usage: java FsShell [-copyFromLocal <localsrc> ... <dst>]

can someone suggest me...

Solution

First the source (local file system) and then the target (HDFS) have to be specified. Run the command as below and it should work.

bin/hadoop dfs -mkdir /hdfs
bin/hadoop dfs -copyFromLocal D:/eclipse/cygwin/home/313159/hadoop-0.19.1/dft/StartUnit.txt /hdfs/StartUnit.txt
