>          Issue Type: Bug
>          Components: Real-time Streaming
>            Reporter: Kun Liu

>            Priority: Major
>             Fix For: v3.1.2
>
>
> In project A, I have created a stream table test_table.
> When I create the table test_table in project B, the table can't be created, but the source config of table in project A lost. 
>  
> The reason: 
> In the `saveStreamingConfig` function, if creating table failed, the config will be dropped in finally phase.
>  
>  
> By design: 
> In order to identity one stream table `StreamingSourceConfig` in the metastore, kylin use the key
> `ResourceStore.STREAMING_V2_RESOURCE_ROOT + "/" + name + ".json"` as the identifier.
> But this design can't work in multi-project.
