Subject [jira] Commented: (HDFS-397) Incorporate storage directories into EditLogFileInput/Output streams
Date Tue, 14 Jul 2009 20:07:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-397?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12731092#action_12731092

Raghu Angadi commented on HDFS-397:

> [...] What's your take on this?

This is expected to be only a minor reorg of code. But it is not, it does not matter weather
those unintended changes are correct or not. btw, the bug would show up during upgrade I guess.
If the patch made sure it didn't change any semantics, either of us need not go through or
completely follow what backup namenode does.

I think a clear and simple bug in the patch is taking a lot of effort to resolve.
It is very unrealistic to expect tests to catch every random bug and typo in a patch  (for
anything I have ever worked on or known.) 

I guess my main point is : there is no change in semantics expected and lets make sure that
is is the case. If there is a functional change, please make that explicit.

Thanks for the references to patch in HDFS-311.. will take a look.
