Subject [jira] [Updated] (HDFS-8529) Add block count metrics to datanode for EC recovery and encoding
Date Thu, 04 Jun 2015 03:59:37 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8529?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Li Bo updated HDFS-8529:
------------------------
    Description: This sub task will add block count metrics to datanode that takes the encoding
and recovery tasks.  (was: HDFS-8425 shows the client writing is not very efficient currently.
One factor is that  when data buffers are full, client suspends until the parities are encoded
and written. This sub task tries to make the two writings concurrently to enhance the efficiency.)
