Hi,
I'm having a lot of difficulty using the hive JDBC driver running in a jetty
container. The hive JDBC driver pulls in a much earlier version of jetty-all,
which causes a failure when the jetty container starts up:
java.lang.IllegalArgumentException: Object of class
'org.eclipse.jetty.webapp.WebAppContext' is not of type
'org.eclipse.jetty.webapp.WebAppContext'. Object Class and type Class are from
different loaders. in

Forcing hive to use the current version of jetty, however, causes a class not
found exception (java.lang.NoClassDefFoundError:
org/apache/http/conn/scheme/SchemeSocketFactory)
So basically this forces me to use the version of jetty that hive is compiled
against. Is there any workaround for this?
I believe I can use a custom jetty class loader to get around this issue, but I
haven't yet fully grokked what this means...
Thanks in advance,
Ben
