linzhongjun updated FLINK-9793:
-------------------------------
Description:
Our company is using flink1.4.2，When the flink program is submitted to run on
yarn,To a yarn - cluster mode，We found that the flink-dist_2.11-1.4.2.jar was
repeatedly uploaded to HDFS，They are in different directories eg;
1..flink/application_1525941455002_539197/flink-dist_2.11-1.4.2.jar
2..flink/application_1525941455002_539197/lib/flink-dist_2.11-1.4.2.jar
Through source code analysis and testing, we found that this code has bugs in
the Linux environment。
java.nio.file.Path file
!(file.getFileName().startsWith("flink-dist")
&&file.getFileName().endsWith("jar")) is Always be true
