### Change Logs In 0.13.0 and latest master, the table service client `BaseHoodieTableServiceClient` is instantiated without any timeline server instance, even if the regular write client has one. This causes the table service client to start a new embedded timeline server and overwrite the write config passed in from the constructor so that the write config points to the newly started timeline server. As the regular write client such as `SparkRDDWriteClient` directly passes in the same writeConfig instance, the regular write client's write config is also affected, causing the regular write client to use the newly started embedded timeline server always, instead of the timeline server instance passed in from the constructor or the one instantiated by the regular write client itself. This means that the Deltastreamer's long-lived timeline server is never going to be used because of this issue. This PR fixes the issue by properly initiating the table service client with the timeline server from the regular write client. ### Impact This makes sure that the timeline server instance passed to the regular write client is used by the write transaction. ### Risk level medium ### Documentation Update N/A ### Contributor's checklist - [ ] Read through [contributor's guide](https://hudi.apache.org/contribute/how-to-contribute) - [ ] Change Logs and Impact were stated clearly - [ ] Adequate tests were added if applicable - [ ] CI passed -- This is an automated message from the Apache Git Service.
