Duo Zhang commented on HBASE-22761:
-----------------------------------
For me I would like to deal with this at upper layer. The behavior of
FanOutOneBlockAsyncDFSOutput is correct, as when issuing the syncComplete call,
we can make sure that the data has been persistent on all the DNs. It is the
upper layer's choice to create a new output ASAP, not the
FanOutOneBlockAsyncDFSOutput.
