> Project: Flink
> Issue Type: Bug
> Components: Connectors / HBase
> Affects Versions: 1.15.0
> Environment: Flink: 1.15.0
> Hbase: 1.4.9

> Priority: Major

> When using the hbase-1.4 version of the connector, the following exception
> will be reported. It seems that the io.netty related package is lost. I found
> that the io.netty package is redirected in maven. When I remove the
> redirection and compile a new one package, found that the task can be
> submitted normally, and then I tested the hbase-2.2 version of the package,
> and found that the task can be submitted normally, I compared the maven
> configuration of 1.4 and 2.2 and it seems that there is not much difference,
> so I am a little confused , why version 1.4 needs to remove redirection
> io.netty to run tasks normally
> {code:java}
> java.lang.RuntimeException: Cannot create connection to HBase.
