### Describe the feature

When the partition reassign is enabled, the writer/reader will get the shuffle handler by the grpc with shuffle manager. that means when the driver is under the high pressure of GC, the write will fail due to the grpc timeout

Research direction

Start from the writer/reader gRPC path that obtains a shuffle handler from the shuffle manager when partition reassignment is enabled. Trace the timeout and retry behavior under driver GC pressure; done means writes no longer fail solely because the initial gRPC request times out.
