Connection Refused error on Hadoop-2.6.0 on Ubuntu 14.10 desktop
running Pseudo Mode
Dear All:
Has anyone encountered this error and if so how have you fixed it other then re-installing Hadoop or re-starting start-dfs.sh when you have already started after boot. Find below
anand_vihar@Latitude-E5540:~$ ssh localhost

anand_vihar@Latitude-E5540:~/hadoop-2.6.0$
I have checked http://wiki.apache.org/hadoop/ConnectionRefused but there is no fix to the problem rather it seems to be a Ubuntu network problem. I have many times killed nanenode/datanode/secondary data note, shutdown and restarted, but this error still appears. The only way seems to be re-installing hadoop. Please advise or refer.
Many thanks,
Regards,

I have checked http://wiki.apache.org/hadoop/ConnectionRefused but there is no fix to the problem rather it seems to be a Ubuntu network problem. I have many times killed nanenode/datanode/secondary data note, shutdown and restarted, but this error still appears. The only way seems to be re-installing hadoop. Please advise or refer.
Many thanks,

run this command in the terminal from root directory
$ sudo nano /etc/hosts (( It will prompt to enter root password))
Later you can comment those lines in hosts files #127.0.1.1
add this line 127.0.0.1 localhost
save the host file and exit

I have checked http://wiki.apache.org/hadoop/ConnectionRefused but there is no fix to the problem rather it seems to be a Ubuntu network problem. I have many times killed nanenode/datanode/secondary data note, shutdown and restarted, but this error still appears. The only way seems to be re-installing hadoop. Please advise or refer.
Many thanks,

I have checked http://wiki.apache.org/hadoop/ConnectionRefused but there is no fix to the problem rather it seems to be a Ubuntu network problem. I have many times killed nanenode/datanode/secondary data note, shutdown and restarted, but this error still appears. The only way seems to be re-installing hadoop. Please advise or refer.
Many thanks,

Re: Connection Refused error on Hadoop-2.6.0 on Ubuntu 14.10 desktop
running Pseudo Mode
Posted by sandeep vura <sa...@gmail.com>.
run this command in the terminal from root directory
$ sudo nano /etc/hosts (( It will prompt to enter root password))
Later you can comment those lines in hosts files #127.0.1.1
add this line 127.0.0.1 localhost
save the host file and exit

Re: Connection Refused error on Hadoop-2.6.0 on Ubuntu 14.10 desktop
running Pseudo Mode
Posted by sandeep vura <sa...@gmail.com>.
run this command in the terminal from root directory
$ sudo nano /etc/hosts (( It will prompt to enter root password))
Later you can comment those lines in hosts files #127.0.1.1
add this line 127.0.0.1 localhost
save the host file and exit

Re: Connection Refused error on Hadoop-2.6.0 on Ubuntu 14.10 desktop
running Pseudo Mode
Posted by sandeep vura <sa...@gmail.com>.
run this command in the terminal from root directory
$ sudo nano /etc/hosts (( It will prompt to enter root password))
Later you can comment those lines in hosts files #127.0.1.1
add this line 127.0.0.1 localhost
save the host file and exit

I have checked http://wiki.apache.org/hadoop/ConnectionRefused but there is no fix to the problem rather it seems to be a Ubuntu network problem. I have many times killed nanenode/datanode/secondary data note, shutdown and restarted, but this error still appears. The only way seems to be re-installing hadoop. Please advise or refer.
Many thanks,

Dear Sandeep:
many thanks. I did find hosts, but I do not have write priveleges, eventhough I am administrator. This is strange. Can you please advise.

I have checked http://wiki.apache.org/hadoop/ConnectionRefused but there is no fix to the problem rather it seems to be a Ubuntu network problem. I have many times killed nanenode/datanode/secondary data note, shutdown and restarted, but this error still appears. The only way seems to be re-installing hadoop. Please advise or refer.
Many thanks,

Dear Sandeep:
many thanks. I did find hosts, but I do not have write priveleges, eventhough I am administrator. This is strange. Can you please advise.
Thanks

Hi Anand,
You should search /etc directory in root not Hadoop directory.

I have checked http://wiki.apache.org/hadoop/ConnectionRefused but there is no fix to the problem rather it seems to be a Ubuntu network problem. I have many times killed nanenode/datanode/secondary data note, shutdown and restarted, but this error still appears. The only way seems to be re-installing hadoop. Please advise or refer.
Many thanks,

anand_vihar@Latitude-E5540:~/hadoop-2.6.0$
I have checked http://wiki.apache.org/hadoop/ConnectionRefused but there is no fix to the problem rather it seems to be a Ubuntu network problem. I have many times killed nanenode/datanode/secondary data note, shutdown and restarted, but this error still appears. The only way seems to be re-installing hadoop. Please advise or refer.
Many thanks,
