Tsz Wo Nicholas Sze commented on HDFS-12720:
--------------------------------------------
Patch looks good. Just some minor comments:
- Should the code below be channel().close().sync()?
{code}
//XceiverClient.close
try {
channelFuture.channel().closeFuture().sync();
} catch (InterruptedException ie) {
LOG.error("close for pipeline:{} interrupted", pipeline, ie);
}
{code}
-* Also, the ie won't be printed to LOG. It should be chanaged to:
{code}
LOG.warn("close for pipeline: " + pipeline + " interrupted", ie);
{code}
-* Since the ie is ignored, let's use warn instead of error.
- Let's add a newRaftGroup(datanodes) to RatisHelper
{code}
static <E extends DatanodeID> RaftGroup newRaftGroup(List<E> datanodes) {
return newRaftGroup(toRaftPeers(datanodes));
}
{code}
so that we can use it in XceiverClientRatis
{code}
public void createPipeline(String clusterId, List<DatanodeID> datanodes)
throws IOException {
final RaftGroup group = RatisHelper.newRaftGroup(datanodes);
LOG.debug("initializing pipeline:{} with nodes:{}", clusterId,
group.getPeers());
reinitialize(datanodes, group);
}
{code}
> Ozone: Ratis options are not passed from KSM Client protobuf helper correctly.

> {{KeySpaceManagerProtocolClientSideTranslatorPB#allocateBlock}} and
> {{KeySpaceManagerProtocolClientSideTranslatorPB#openKey}} do not pass the
> ratis replication factor and replication type to the KSM server. this causes
> the allocations using ratis model to resort to standalone mode even when
> Ratis mode is specified.
