Poroblem with hadoop appache configuration error connection refused

[Mahdi Bazargani <ma...@yahoo.com.INVALID>]

Dear Hadoop users,

I am trying to configure hadoop on my windows seven using Cygwin on just one node which named master and slave to localhost
My configuration files are as bellow:
==================hdf-site<configuration> <property>  <name>hadoop.tmp.dir</name>  <value>/home/bazargan/hadoop-1.2.1/tmp</value>  <description>A base for other temporary directories.</description></property> <property>  <name>dfs.data.dir</name>  <value>/home/bazargan/data</value>  <description>Comma separated list of paths on the local filesystem of aDataNode where it should store its blocks. </description></property><property><name>dfs.name.dir</name><value>/home/bazargan/name</value> </property> <property>  <name>dfs.default.name</name>  <value>hdfs://localhost:54310</value>  <description>The name of the default file system.  A URI whose  scheme and authority determine the FileSystem implementation.  The  uri's scheme determines the config property (fs.SCHEME.impl) naming  the FileSystem implementation class.  The uri's authority is used to  determine the host, port, etc. for a filesystem.</description></property> <property>  <name>dfs.replication</name>  <value>3</value>  <description>Default block replication.  The actual number of replications can be specified when the file is created.  The default is used if replication is not specified in create time.  </description></property>

when I try to access lochost:50070 it works perfectly but when I want to access localhost:50030 I got connection refused error.

I really don't know what is causing the error (in log files I also dont see any error for example below is my log of datanode..ulimit -a for user Mahdicore file size          (blocks, -c) unlimiteddata seg size           (kbytes, -d) unlimitedfile size               (blocks, -f) unlimitedopen files                      (-n) 256pipe size            (512 bytes, -p) 8stack size              (kbytes, -s) 2032cpu time               (seconds, -t) unlimitedmax user processes              (-u) 256virtual memory          (kbytes, -v) unlimited

I also turned off my firewall.
I really appreciate if anyone can help me.
Thanks.
