Subject Re: [VOTE] Apache Trafodion release 2.0.0 ready for release - release candidate 1
Date Tue, 17 May 2016 21:44:54 GMT
Hi Amanda,

Alas, that did not work:

*** WARNING: All errors must be fixed before Installation will continue
TRAFODION NODE LIST
***ERROR:  trafodion-2.novalocal trafodion-3.novalocal does not have sudo
access.
***ERROR: Must have sudo access on all nodes.

[centos@trafodion-1 installer]$ cat my_config | grep MY_NODES
export MY_NODES="-w trafodion-1.openstack -w trafodion-2.openstack -w
trafodion-3.openstack"


Also, the config files states:

# another list of the same nodes in NODE_LIST but specified in a pdsh
usable format
# i.e.  "-w centos-cdh[1-6]"  or "-w node1 -w node2 -w node3"
export MY_NODES="-w trafodion-1.openstack -w trafodion-2.openstack -w
trafodion-3.openstack"


I thought the example I showed illustrates that passwordless ssh and sudo
are set up correcty. Try this:

[centos@trafodion-1 installer]$ ssh trafodion-2.openstack
Last login: Tue May 17 21:38:10 2016 from 10.1.30.28
[centos@trafodion-2 ~]$ sudo cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4
localhost4.localdomain4
::1         localhost localhost.localdomain localhost6
localhost6.localdomain6

10.1.30.28  trafodion-1.openstack trafodion-1
10.1.30.107 trafodion-2.openstack trafodion-2
10.1.30.108 trafodion-3.openstack trafodion-3
[centos@trafodion-2 ~]$ exit
logout
Connection to trafodion-2.openstack closed.
[centos@trafodion-1 installer]$ ssh trafodion-3.openstack
Last login: Tue May 17 21:38:31 2016 from 10.1.30.28

10.1.30.28  trafodion-1.openstack trafodion-1
10.1.30.107 trafodion-2.openstack trafodion-2
10.1.30.108 trafodion-3.openstack trafodion-3

Thanks,

Gunnar
