Hi Guys,
I am new to SQOOP and am stuck at the 5 minute demo. This is with
sqoop-1.99.3-bin-hadoop200 on a mac. The error I see is in the
catalina.out. I searched the web and the workaround suggested
("org.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES =
false") doesn't seem to help. The sqoop.log has no errors, but says
"shutting down". Any ideas?
