Hi guys I know you guys want to keep costs down, but why go through all the effort to setup ec2 instances when you deploy EMR it takes the time to provision and setup the ec2 instances for you. All configuration then for the entire cluster is done on the master node of the particular cluster or setting up of additional software that is all done through the EMR console. We were doing some geospatial calculations and we loaded a 3rd party jar file called esri into the EMR cluster. I then had to pass a small bootstrap action (script) to have it distribute esri to the entire cluster.
Why are you guys reinventing the wheel? --- Regards, Jonathan Aquilina Founder Eagle Eye T On 2015-03-06 03:35, Alexander Pivovarov wrote: > I found the following solution to this problem > > I registered 2 subdomains (public and local) for each computer on > https://freedns.afraid.org/subdomain/ [1] > e.g. > myhadoop-nn.crabdance.com [2] > myhadoop-nn-local.crabdance.com [3] > then I added cron job which sends http requests to update public and local ip > on freedns server hint: public ip is detected automatically ip address for > local name can be set using request parameter &address=10.x.x.x (don't forget > to escape &) > > as a result my nn computer has 2 DNS names with currently assigned ip > addresses , e.g. > myhadoop-nn.crabdance.com [2] 54.203.181.177 > myhadoop-nn-local.crabdance.com [3] 10.220.149.103 > > in hadoop configuration I can use local machine names to access my cluster > outside of AWS I can use public names > > Just curious if AWS provides easier way to name EC2 computers? > > On Thu, Mar 5, 2015 at 5:19 PM, Jonathan Aquilina <[email protected]> > wrote: > > I dont know how you would do that to be honest.
