Subject Re: spark 1.2 ec2 launch script hang
Date Wed, 28 Jan 2015 20:30:08 GMT
It was only hanging when I specified the path with ~ I never tried relative.

Hanging on the waiting for ssh to be ready on all hosts. I let it sit for
about 10 minutes then I found the StackOverflow answer that suggested
specifying an absolute path, cancelled, and re-run with --resume and the
absolute path and all slaves were up in a couple minutes.

(I've stood up 4 integration clusters and 2 production clusters on EC2
since with no problems.)
