Subject [jira] [Updated] (HDFS-3814) Make the replication monitor multipliers configurable in 1.x
Date Sun, 19 Aug 2012 03:02:38 GMT

     [ https://issues.apache.org/jira/browse/HDFS-3814?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Harsh J updated HDFS-3814:
--------------------------

    Release Note: 
This change adds two new configuration parameters. 
# {{dfs.namenode.invalidate.work.pct.per.iteration}} for controlling deletion rate of blocks.
# {{dfs.namenode.replication.work.multiplier.per.iteration}} for controlling replication rate.
This in turn allows controlling the time it takes for decommissioning.

Please see hdfs-default.xml for detailed description.
