我用doucmentation创建了这个示例程序https://ci.apache.org/projects/flink/flink-docs-release-0.8/programming_guide.html#introduction
在ide中运行时出现以下错误

log4j:WARN No appenders could be found for logger (org.apache.flink.api.scala.ClosureCleaner$).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
