Subject [jira] [Updated] (HDFS-8938) Refactor BlockManager in blockmanagement
Date Thu, 27 Aug 2015 05:12:46 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8938?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mingliang Liu updated HDFS-8938:
--------------------------------
    Description: 
This jira tracks the effort of refactoring inner classes {{BlockManager$BlockToMarkCorrupt}}
and {{BlockManager$ReplicationWork}} in {{hdfs.server.blockmanagement}} package. As the line
number of {{BlockManager}} is getting larger than 2000, we can move those two inner classes
out of the it.

Meanwhile, the logic in method {{computeReplicationWorkForBlocks}} can be simplified if we
extract code sections to _schedule replication_ and to _validate replication work_ to private
helper methods respectively.
