Subject [jira] Updated: (HDFS-658) Block recovery for primary data-node
Date Mon, 28 Sep 2009 22:57:16 GMT

     [ 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

This version 
- removes all occurrences of deprecated methods {{updateBlock()}} and {{getBlockMetaDataInfo()}}
in the tests.
- {{initReplicaRecovery()}} returns null if replica is not found on the data-node instead
of throwing {{ReplicaNotFoundException}}, because this seems to be a normal (not exceptional)
condition during replica recovery. 
- Also fixed a block report problem, which caused occasional failure of {{TestDatanodeBlockScanner}}
