Kun Liu updated KYLIN-4921:
---------------------------
Description:
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.
