Subject [jira] Commented: (HDFS-265) Revisit append
Date Wed, 29 Jul 2009 20:54:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-265?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12736822#action_12736822
] 

Tsz Wo (Nicholas), SZE commented on HDFS-265:
---------------------------------------------

Found 2 typos:
- There is only one new test case in Pipeline_FI.  The test numbers are changed and there
is no Pipeline_FI_25 in the new test plan.
- HADOOP-265 should be HDFS-265

> 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.
