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>
</configuration>

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

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