Suresh Srinivas commented on HADOOP-7557:
-----------------------------------------
bq. The reason we removed Avro was that implementing RpcEngine alone was no
longer sufficient: there were assumptions that Protobuf was used in other
places in the code. RpcEngine is currently a broken abstraction, providing a
false claim of plugability.
This is not correct.
I think quite a bit of discussion has already happened around this. See the
comment:
https://issues.apache.org/jira/browse/HDFS-2664?focusedCommentId=13168625&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13168625
BTW look at HDFS-1623 branch. There protocol implementations of both Writable
and protobuf co-exist in the same NN server. Look at
TestMultipoleProtocolServer test. Multiple versions of the same protocol exist.
