Hi Pawar,
can you share your /etc/hosts file ?
sure,
as below:
namenode (Fedora-19 192.168.1.217)
===============================================
#cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4
localhost4.localdomain4
::1 localhost localhost.localdomain localhost6
localhost6.localdomain6
192.168.1.244 hadoop1
192.168.1.248 hadoop2
192.168.1.217 Fedora-19
===============================================
datanode1 (hadoop1 192.168.1.244)
===============================================
#cat /etc/hosts
127.0.0.1 localhost
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Hi guys,
I had a small cluster including 1 namenode and 2 datanodes
I got webhdfs enabled
and I sent an OPEN request as follow:
curl -i -L 'http://namenode:50070/webhdfs/v1/path/to/somefile?op=OPEN'
It redirected to
http://datanode:50075/webhdfs/v1/path/to/somefile?op=OPEN
what weird was that the redirected URL used "localhost" as its netloc,
the URL is like
"http://localhost:50075/webhdfs/v1/path/to/somefile?op=OPEN";<http://localhost:50075/webhdfs/v1/path/to/somefile?op=OPEN>
I have checked the config files and I didn't figured out what influenced
it.
In addiction when I check the active data nodes via
"http://namenode:50070/dfsnodelist.jsp?whatNodes=LIVE";<http://namenode:50070/dfsnodelist.jsp?whatNodes=LIVE>
The node column' datanodes' name were all "localhost"
why?
Any body knows what's going on about that?
Thanks,
Dou
