[jira] Updated: (HDFS-658) Block recovery for primary data-node

["Konstantin Shvachko (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HDFS-658?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Konstantin Shvachko updated HDFS-658:
-------------------------------------

    Attachment: primaryRecovery.patch

Here is the patch for primary recovery.
The primary uses InterDatanodeProtocol fore recovery communication with other node. There are two new methods in the protocol, which are intended to replace the old two.
New method {{initReplicaRecovery()}} is used instead of the old one {{getBlockMetaDataInfo()}},
{{updateReplicaUnderRecovery()}} is used instead of the old {{updateBlock()}}.
Old methods are deprecated so I expect some javac warnings about it. I plan to remove old methods in the next patch.
