Subject [jira] [Commented] (HDFS-1958) Format confirmation prompt should be more lenient of its input
Date Thu, 19 May 2011 17:36:47 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1958?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13036311#comment-13036311
] 

Tsz Wo (Nicholas), SZE commented on HDFS-1958:
----------------------------------------------

> well, fsck for example supports either 'y' or 'Y' for yes, and 'n' or 'N' for no.

fsck and format are different: it is okay to accidentally click "y" for fsck but not for format.

I was asking if this is a good feature in [my previous comment|https://issues.apache.org/jira/browse/HDFS-1958?focusedCommentId=13035881&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13035881].
 I tried to change a few years back but I heard one argument saying that the command was deliberately
designed for preventing accidentally format.

BTW, I think this should be classified as a "newbie" issue once we have decided to do it.

> As reported on the mailing list, the namenode format prompt only accepts 'Y'. We should
also accept 'y' and 'yes' (non-case-sensitive).
