Tsz Wo Nicholas Sze commented on HDFS-9050:
-------------------------------------------

What are the advantages by restricting updatePipeline RPC to only update the GS of the block?

> The only usage of the call is in {{DataStreamer#updatePipeline}}, where {{newBlock}}
differs from current {{block}} only in GS.
> Basically the RPC call is not supposed to update the {{poolID}}, {{ID}}, or {{numBytes}}
of the block on NN.
