Hello:
I am new to flink, and I copy the official Hbase connector examples from
source
flink/flink-connectors/flink-hbase/src/test/java/org/apache/flink/addons/hbase/example/HBaseWriteExample.java
and run in a yarn-cluster with the command:
bin/flink run -m yarn-cluster -yn 2 -c {class-path-prefix}.HBaseWriteExample
{my-application}.jar
What I have get is:
------------------------------------------------------------
The program finished with the following exception:
org.apache.flink.client.program.ProgramInvocationException: The main method
caused an error.
