Date Mon, 29 Mar 2010 23:31:28 GMT

     [ https://issues.apache.org/jira/browse/HDFS-265?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hairong Kuang resolved HDFS-265.
--------------------------------

    Resolution: Fixed

A few recent updates to the jira:
1. Block recovery tests have been committed to both 0.21 and the trunk.
2. Stress/performance/scalability tests are going to be tracked in HDFS-708.

Since all sub-tasked are committed, let me close this jira.

> HADOOP-1700 and related issues have put a lot of efforts to provide the first implementation
of append. However, append is such a complex feature. It turns out that there are issues that
were initially seemed trivial but needs a careful design. This jira revisits append, aiming
for a design and implementation supporting a semantics that are acceptable to its users.
