exceeded the 80 characters length limit and was truncated.

flink任务在idea调试时没有问题，但提交到standalone集群上运行时，发现没有数据。看日志发现下面这段信息：

2020-06-04 21:05:05,897 WARN  org.apache.flink.metrics.MetricGroup                          - The operator name DataSource (at createInput(ExecutionEnvironment.java:576) (com.asn.re.warehouse.dws.source.DWS_ReceiptBillEntry_IPF)) exceeded the 80 characters length limit and was truncated.

关键信息就是这一句 exceeded the 80 characters length limit and was truncated。自定义的inputformat名称过长，超过80个字节，被自动阶段，然后处理从running转成finished。。。

6月5日补充

这个异常是flink默认的指标监控中的一项，不会影响程序的运行。

这里之所以配跑完任务但没有数据，是因为打包时没有把flink依赖的一些包排除掉，scope设置成provided即可。
