Hi Sathya, It wont help you even little bit in unsubscribing from Hadoop list even if you send a zillion unsubscribe email to [email protected] address. Unsubscribe instructions are present on the Apache Hadoop website.
Here's what you are supposed to do for unsubscribing: To unsubscribe, you have to send a mail to user-unsubscribe @hadoop.apache.org with subject line as unsubscribe. ~Anil On Fri, Aug 10, 2012 at 9:09 PM, sathyavageeswaran <[email protected]>wrote: > unsubscribe**** > > ** ** > > *From:* Arjun Reddy [mailto:[email protected]] > *Sent:* 10 August 2012 23:25 > *To:* [email protected] > *Subject:* Re: Problem running PI example in Hadoop 2.0.0**** > > ** ** > > I removed the entry 127.0.1.1 in /etc/hosts on all the nodes and the > cluster is working fine now.
