Subject [jira] [Commented] (HDFS-2538) option to disable fsck dots
Date Tue, 25 Feb 2014 18:14:23 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13911818#comment-13911818

Akira AJISAKA commented on HDFS-2538:
-------------------------------------

The test failure is not related to the latest patch.

bq. What could possibly break by removing the dots?
Unfortunately, users may use the scripts to run fsck which assume that dots are output in
the console.

[~kamrul], can you please update the document also? The document is in hadoop-common-project/hadoop-common/src/site/apt/CommandsManual.apt.vm.
I'm +1 once it is addressed.

> this patch turns the dots during fsck off by default and provides an option to turn them
back on if you have a fetish for millions and millions of dots on your terminal.  i haven't
done any benchmarks, but i suspect fsck is now 300% faster to boot.
