Subject [jira] [Commented] (HAMA-717) Compatibility with HDFS 2.0
Date Thu, 24 Jan 2013 01:14:11 GMT

    [ https://issues.apache.org/jira/browse/HAMA-717?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13561299#comment-13561299
] 

Edward J. Yoon commented on HAMA-717:
-------------------------------------

Quick solution is copy&paste Hadoop 1.0 RPC to org.apache.hama.ipc package. At least,
this RPC's scalability was verified.

Since we have pluggable messenger interface, we can change RPC for inter-peer communication
later (I think this is not urgent).
