Subject [jira] [Commented] (HADOOP-8230) Enable sync by default and disable append
Date Mon, 07 May 2012 15:04:51 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8230?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13269678#comment-13269678

Koji Noguchi commented on HADOOP-8230:
--------------------------------------

bq. , but what is that use case?

I'm probably a minority here but I do want the "an option to disable durable sync" not because
it could be buggy but because it could be too stable compared to 0.23/2.0.  Before moving
all of our non-HBase clusters to 2.0, we might use 1.1 for some time.  During this period,
I do not want some production projects to start relying on the sync features then find some
regression/difference on 2.0 blocking our upgrade schedule.

> Per HDFS-3120 for 1.x let's:
> - Always enable the sync path, which is currently only enabled if dfs.support.append
is set
> - Remove the dfs.support.append configuration option. We'll keep the code paths though
in case we ever fix append on branch-1, in which case we can add the config option back
