If this was in the zone file:
gdocs 3600 IN CNAME ghs.google.com
It ended up like this in Route 53:
I can confirm this bug as well :-/
I can confirm this is a bug.. in your zone files! ;)
Records must be terminated with a period, otherwise they are relative records.
"Domain names in the zone files can be one of two types, either
absolute or relative. An absolute name is the fully qualified domain
name and is terminated with a period. A relative name does not
terminate with a period, and the current default domain is appended
to it. The default domain is usually the name of the domain that was
specified in the boot file that loads each zone."
hmmm, ok, well that's direct export from GoDaddy. Perhaps you could at least supply a flag that would not append the domain like import --no-append or something.
Suggest either manually fix file or running perl over the GoDaddy export to fix, this should do the trick:
perl -pe 's/(CNAME .+)(?!.)$/$1./i' broken.txt > fixed.txt
I'll add a note to the README.
FWIW, I had this same issue exporting from one account's route53 and importing to another. I checked my source zonefile (not the export from cli53 export, but the route53 api response) and confirmed it was missing the period. It turns out to be my fault: I have cnames without the trailing period -- which have worked, apparently, all this time, despite being wrong.
I'd suggest changing the readme (which I read, but skipped the relevant section due to GoDaddy mention) to instead note that it's useful to check whether exported cnames are defined correctly (that is, with either a trailing period or intentionally relative).
Also, the regex is not quite right - it didn't allow for hostnames with hyphens:
perl -pe 's/(CNAME\s+[-a-zA-Z0-9.-]+)(?!.)$/$1./i'
perl -pe 's/(CNAME\s+[a-zA-Z0-9.-]+)(?!.)$/$1./i'
