Tsz-wo Sze commented on RATIS-1115:
-----------------------------------
[~amaliujia], thanks for filing this JIRA. We need to think about how to
handle error case carefully. In particular, how would the system recover from
the error?
For RATIS-1104, we send an unsuccessful reply when the bytesWritten values are
mismatched. However, we should also think about how should the stream
continues. Or, we may close it and cleanup everything. Currently, if
bytesWritten values are mismatched, the system cannot recover from it.
It probably is a good idea to continue the error handling work in this JIRA.
Let's have a design discussion.
[~yjxxtd], you probably want to join the discussion on error handling.
