当在提交一个flink任务报如下的错误时：

Caused by: java.io.FileNotFoundException: /home/wc.txt (没有那个文件或目录)
        at java.io.FileInputStream.open0(Native Method)
        at java.io.FileInputStream.open(FileInputStream.java:195)
        at java.io.FileInputStream.<init>(FileInputStream.java:138)
        at org.apache.flink.core.fs.local.LocalDataInputStream.<init>(LocalDataInputStream.java:50)
        at org.apache.flink.core.fs.local.LocalFileSystem.open(LocalFileSystem.java:134)
        at org.apache.flink.api.common.io.FileInputFormat$InputSplitOpenThread.run(FileInputFormat.java:1053)

原因是：你的 taskManager 有三台，你的数据只在本地存放一份，所以需要将数据分发给 bigdata02 和 bigdata03

分发一下即可

xsync.sh /home/wc.txt
