Ugh. It's -k, not --k.
So, this bit of code could likely be more useful:
} catch (IllegalArgumentException e) {
log.error(e.getMessage());
CommandLineUtil.printHelpWithGenericOptions(group);
return null;
}
Since, at least on EMR, the logs tend to get buried and it writes it out to
syslog, not stderr or stdout.
I have it running now by logging into the EMR instance using SSH and then I
also specifically uploaded my Vector file to HDFS by hand. In other words, I'm
not using the remote Ruby CLI just yet.
Progress. Sigh.
