> Currently, when I disable hive table source parallelism inference using configuration  and set parallelism.default: 100. 
> {code:java}
> table.exec.hive.infer-source-parallelism: false 
> parallelism.default: 100{code}
> The result is that the parallelism of hive table source is {*}1{*}, and the configuration of the default parallelism is not effective.
> I will optimize this problem. In the future, when disable hive table source parallelism inference ，the  parallelism of hive table source will be determined according to the following order：
>  
> 1. If table.exec.resource.default-parallelism is set, the configured value will be used
> 2. If parallelism.default is set, the configured value is used
> 3. If the above two configuration items are not set, the default value is 1
