Tsz Wo Nicholas Sze commented on HDFS-6739:
-------------------------------------------
Thanks Jing for reviewing the patch.
For #1, the import fix is required since the package of DatanodeStorageProto is
changed.
{code}
-import
org.apache.hadoop.hdfs.protocol.proto.DatanodeProtocolProtos.DatanodeStorageProto;
...
+import org.apache.hadoop.hdfs.protocol.proto.HdfsProtos.DatanodeStorageProto;
{code}
I will fix #2 and #3.
> Besides, do we need to consider the scenario that the
> getDatanodeStorageReport response size exceeds the max response size? ...
This a good point. Let's fix it in a separated JIRA as you suggested.
> Add getDatanodeStorageReport to ClientProtocol
