Tsz Wo Nicholas Sze commented on HDDS-247:
------------------------------------------
For performance reason, ChunkGroupOutputStream/ChunkOutputStream may not be
thread safe as the Java OutputStream subclasses are generally non-thread-safe.
If users want thread safe, they can easily synchronize it themselves.
How about we make both of them non-thread-safe?

> In case of ongoing writes by Ozone client to a container, the container might
> get closed on the Datanodes because of node loss, out of space issues etc. In
> such cases, the operation will fail with CLOSED_CONTAINER_IO exception. In
> cases as such, ozone client should try to get the committed length of the
> block from the Datanodes, and update the OM. This Jira aims to address this
> issue.
