Tom White commented on HADOOP-1634:
-----------------------------------
I've been using ec2-api-tools-1.2-7546 (the previous release I think - the one
you're using came out a couple of weeks ago). I'll see if your patch fixes the
problem using both versions of the tools.
BTW which OS are you using?

> With Amazon 'ec2-api-tools-1.2-11797' and Hadoop 0.13.0 the output from
> ec2-describe-instances is being incorrectly AWK'd on the last few lines of
> the launch-hadoop-cluster script.
> Specifically, on the
> """
> MASTER_EC2_HOST=`ec2-describe-instances | grep INSTANCE | grep running | awk
> '{if ($7 == 0) print $4}'`
> """
> line, it should be comparing column $8 rather than column $7.
> When this command fails, the hostname of the master doesn't get set correctly
> and the IP lookup finds incorrect results. The last lines of output from the
> script look something like this:
> """
> Appointing master
> Master is . Please set up DNS so blah.gotdns.org points to D.ROOT-SERVERS.NET.
> I.ROOT-SERVERS.NET.
> F.ROOT-SERVERS.NET.
> M.ROOT-SERVERS.NET.
> J.ROOT-SERVERS.NET.
> C.ROOT-SERVERS.NET.
> H.ROOT-SERVERS.NET.
> E.ROOT-SERVERS.NET.
> A.ROOT-SERVERS.NET.
> K.ROOT-SERVERS.NET.
> G.ROOT-SERVERS.NET.
> B.ROOT-SERVERS.NET.
> L.ROOT-SERVERS.NET..
> Press return to continue.
