Subject [jira] Commented: (HADOOP-2658) Design and Implement a Test Plan to support appends to HDFS files
Date Fri, 10 Oct 2008 00:50:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2658?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12638457#action_12638457
] 

Chris Douglas commented on HADOOP-2658:
---------------------------------------

* Instead of local blocks, each of these should probably be separate tests. All can use the
same static MiniDFSCluster using TestSetup, as in TestDatamerge, TestReduceFetch, etc.
* In TC11, does it make sense to check the return value of fs.rename?
* Since it's essentially dead code in trunk, it might make more sense to make TC3 part of
HADOOP-4379 instead of enabling it once it can be expected to pass

> HADOOP-1700 describes the design of supporting appends to HDFS files. This feature needs
extensive testing, especially because the design explicitly analyzes many failure scenarios.
A detailed test plan and test cases are needed to make this feature a reality.
