Datanode failover for write block

[junjieqian]

Hi, we hit a problem in block_writer, that if local datanode fails, the write operation would fail with connection failure too.

I tried implement a similar failover for block write as block read. The blockWriter can find the next available datanode, but always fails with Error from datanode: ERROR (), which is from readBlockOpResponse.

Can you give me some suggestions on how to fix this? Or did I miss something in writeBlockWriteRequest, so the client cannot response correctly?

Thanks

@junjieqian : getting the same error. I see the issue is closed, can you give some leads ? Thanks.
