Subject [jira] [Commented] (HDFS-2298) TestDfsOverAvroRpc is failing on trunk
Date Tue, 30 Aug 2011 11:41:37 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13093664#comment-13093664

Uma Maheswara Rao G commented on HDFS-2298:
-------------------------------------------

Hi Aaron,
 
 Looks Avro does not support multiple APIs with same name
http://web.archiveorange.com/archive/v/du1upKgQKN4KYfuW7tng

 But we have the cases in NameNodeProtocols.

{code}
public interface NamenodeProtocols
  extends ClientProtocol,
          DatanodeProtocol,
          NamenodeProtocol,
          RefreshAuthorizationPolicyProtocol,
          RefreshUserMappingsProtocol,
          GetUserMappingsProtocol {
{code}

One more observation is that reportedBadBlocks, versionRequest and etc.. present in ClientProtocol,
DatanodeProtocol. I think this case also will not be allowed.


Since we have such scenarios to support, we may need to check with Avro.
we can file one JIRA in AVRO or you have some workaround for this?


Thanks
Uma
