Subject [jira] Updated: (HDFS-585) Datanode should serve up to visible length of a replica for read requests
Date Wed, 09 Sep 2009 21:53:57 GMT

     [ https://issues.apache.org/jira/browse/HDFS-585?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tsz Wo (Nicholas), SZE updated HDFS-585:
----------------------------------------

    Attachment: h585_20090909.patch

h585_20090909.patch: use getBytesOnDisk() instead of file length.

> 2. Should we have unit tests testing reading from an unclosed file?
The read function is not yet completed.  So it is hard to write unit tests for this.  If you
insist, I don't mind to spend time on adding unit tests.

> As a part of the design in HDFS-265, datanodes should return all bytes within the visible
length of a replica to the DFSClient in order to support read consistency.
