We're still working on better facilities to look at Sqoop2 logs, but there are currently a few locations you can look (depending on your error). I'm assuming Sqoop2 starts fine, but a job you're running is failing. If that is the case, then your logs should be under /var/log/sqoop2/ and in its associated task/attempt logs. You can view these logs through the Yarn UIs (usually on port 8088. e.g. http://example.com:8088) or through Hue (http://gethue.com/).
