请教一个问题:sqoop 1.99.6启动不了,报错:log4j:ERROR A "org.apache.log4j.ConsoleAppender" object is not assignable to a "org.apache.log4j.Appender" variable.
log4j:ERROR The class "org.apache.log4j.Appender" was loaded by
log4j:ERROR [org.apache.catalina.loader.StandardClassLoader@27aed7c1] whereas object of type
log4j:ERROR "org.apache.log4j.ConsoleAppender" was loaded by [WebappClassLoader
