Description

Current block write operation's header has the following fields:
blockId blockGS pipelineSize isRecovery clientName hasSource source #datanodesInDownStreamPipeline downstreamDatanodes
I'd like to change the header to be
blockId blockGS pipelineSize clientName flags blockMinLen blockMaxLen newGS hasSource source #datanodesInDownStreamPipeline downstreamDatanodes

With this protocol change, pipeline recovery will be performed when a mew pipeline is set up.
