Hi,
Make your host file like :
127.0.0.1 localhost
10.86.29.24 chn-29-24.mmt.mmt chn-29-24
if you have not specified 6500 any where den y its trying to connect to it
??
localhost/127.0.0.1:6500
*In core-site.xml please make some entries like :*
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/home/shashwat/hdfs/tmp</value>
</property>
<property>
<name>hadoop.proxyuser.oozie.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.oozie.groups</name>
<value>*</value>
</property>
</configuration>
*and in mapred-site.xml something like this :*
<configuration>
<property>
<name>mapred.job.tracker</name>
<value>localhost:9001</value>
</property>
</configuration>
*and in hdfs-site.xml something like this :*
<configuration>
<property>
<name>dfs.name.dir</name>
<value>/home/<your user name here>/hdfs/name</value>
</property>
<property>
<name>dfs.data.dir</name>
<value>/home/<your user name here>/hdfs/data</value>
</property>
<property>
<name>dfs.datanode.max.xcievers</name>
<value>4096</value>
</property>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
</configuration>
You have 10.86.29.24 chn-29-24.mmt.mmt chn-29-24 this in your
host file so i am supposing that 10.86.29.24 as the ip of your current
system right?? then instead of localhost you can gife chn-29-24.mmt.mmt
or chn-29-24, after making these changes delete your hdfs folder if
know where it is or just format the namenode and check if it working.
also do
chown -R <your user name> <your hadoop folder name>
chmod -R 755 <your hadoop folder name>
to change the rights of the folder.
and before trying any thing else
ping on localhost
ping on your ip
ping on your hostname
if all above are working
ssh to all above if it working then you can proceed
