Subject Re: CopyTable fails on copying between two secured clusters
Date Fri, 09 Sep 2016 17:47:53 GMT
Hi Frank,

I dont know your exact use case. But, I have successfully run copyTable
across *2 secure* clusters back in 2013-2014 on a CDH distro cluster.
Unfortunately, I dont remember the settings or command that we ran to do
that since it was at my previous job.

Thanks,
Anil Gupta
