Description

Currently, while a block is allocated from OM, the request is forwarded to SCM. However, even though the pipeline information is present with the OM for block allocation, this information is passed through to the client.

This optimization will help in reducing the number of hops for the client by reducing 1 RPC round trip for each block allocated.
