Subject [jira] [Commented] (SQOOP-1821) DOC: Add instructions on how-to create a external connector and make it work in Sqoop
Date Thu, 04 Dec 2014 18:00:17 GMT

    [ https://issues.apache.org/jira/browse/SQOOP-1821?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14234416#comment-14234416

Vinoth Chandar commented on SQOOP-1821:

The problem with tomcat is the mess or sophistication (depending on how much tomcat you know),
around class loaders (http://www.mulesoft.com/tcat/tomcat-classpath) 

Jarek is  right : All the sqoop server needs to do to load external jars should a call to
the JVM class loader on startup.. 

Can we switch to something like Netty instead? (I see a ticket for Jetty already). If REST
endpoints is all that Tomcat is buying us, then probably not worth it. Could simplify this
a lot.
