[Solved] Flink1.12 integration Hadoop 3. X error: java.lang.RuntimeException…

Flink1.12 integration Hadoop 3. X error reporting

Due to the needs of the project, it is necessary to carry out rule early warning for a period of time, so first install the Flink cluster and Hadoop on the alicloud server of the project, but when running the official website example, an error is directly reported. The specific information is as follows:

Only later did Baidu find that it needed a jar package to bridge Flink and HDFS, so it put the two jar packages into the Lib of Flink.

Then, when starting, an error will still be reported, and the information is as follows:

[[email protected] flink-1.12.0]# bin/flink run  examples/batch/WordCount.jar --input hdfs://k8s-master:9000/test/word.txt --output hdfs://k8s-master:9000/test/result.txt  --parallelism 2

Since I install the Flink cluster here, I can package the two jars in SCP to the other two nodes and they can run normally.
