Hi Team,

I install RDO Grizzly version on my Desktop having following configuration -

OS - Redhat6.4 RAM - 12GB HDD - 300GB Network card - 1 [172.26.35.81/255.255.254.0] <- My network settings are set to DHCP.

Following is my current ifconfig command o/p -

[root@openstack ~]# ifconfig br100 Link encap:Ethernet HWaddr FE:16:3E:07:7B:BF

Make sure that the security group allows access to 50070 & 50030.

If that doesn't work, login via ssh and make sure the services are up.

If they are, there may be a routing issue.

What's the output of openstack-status and are you using nova-networking or neutron?

As checked -

  1. 50070 & 50030 ports are running in netstat and listening
  2. ssh is working fine and namenode, datanode & mapred are working fine
  3. It seems to be network issue since -

i created network using following command -

nova floating-ip-bulk-create nova 172.26.35.0/23

But after assigning the floating ip to instance it still shows the network as "172.26.35.82/32".

It should take "172.26.35.0/23" !! Pls find the below o/p -

eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
link/ether 00:16:41:3e:cd:2a brd ff:ff:ff:ff:ff:ff
inet 172.26.35.81/23 brd 172.26.35.255 scope global eth0
inet 172.26.35.82/32 scope global eth0

Is there any mistake i am doing ?

++++ -

I just tried to check o/p of #ipaddr command - and found that its taking subnet mask of 32 instead of 24 as i defined in nova command -

[root@openstack ~]# ip addr 1: lo: <loopback,up,lower_up> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet 169.254.169.254/32 scope link lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <broadcast,multicast,up,lower_up> mtu 1500 qdisc mq state UP qlen 1000 link/ether 00:16:41:3e:cd:2a brd ff:ff:ff:ff:ff:ff inet 172.26.35.81/23 brd 172.26.35.255 scope global eth0 inet 172.26.35.82/32 scope global eth0 inet6 fe80::216:41ff:fe3e:cd2a/64 scope link valid_lft forever preferred_lft forever

For ports 50070 & 50030, does the secgroup applied to the nodes allow access?

nova secgroup-list-rules default

+-------------+-----------+---------+-----------+--------------+ | IP Protocol | From Port | To Port | IP Range | Source Group | +-------------+-----------+---------+-----------+--------------+ | tcp | 22 | 22 | 0.0.0.0/0 | | +-------------+-----------+---------+-----------+--------------+

Above is an example of a group that allows ssh and does not allow 50070 | 50030.

You can go into Horizon and add rules for 50070 and 50030 if they are missing.
