为什么yarn.provided.lib.dirs在flink1.11 yarn提交不生效？

flink1.11 on yarn模式，我提前将flink  lib下的依赖及自定义函数jar上传到hdfs上，提交时使用yarn.provided.lib.dirs  指定hdfs的依赖路径。原本设想程序中使用反射去寻找自定义函数的类并且实例化，但是提交时报错，程序并没有找到自定义函数的路径 

提交命令:/usr/hdp/flink1.11/bin/flink run -m yarn-cluster -d -ynm udf-test -yD  yarn.provided.lib.dirs=hdfs://ip:8020/flink-yarn/jars -c  com.ly.common.udf.demo.FlinkUDFDemo /data/bigdata/jars/udf-test.jar 

相关信息如下:  2020-12-22 08:41:11,157 INFO org.apache.flink.yarn.cli.FlinkYarnSessionCli   [] - Dynamic Property set:  yarn.provided.lib.dirs=hdfs://chaitin/flink-yarn/jars  2020-12-22 08:41:11,157 INFO org.apache.flink.yarn.cli.FlinkYarnSessionCli   [] - Dynamic Property set:  yarn.provided.lib.dirs=hdfs://chaitin/flink-yarn/jars  -- class path: /usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib
