Subject [jira] Commented: (HADOOP-3064) Exception with file globbing closures
Date Sat, 22 Mar 2008 00:21:24 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3064?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12581228#action_12581228
] 

Tsz Wo (Nicholas), SZE commented on HADOOP-3064:
------------------------------------------------

- should we use String.replaceAll(...) instead of String.replace(...)?

-  could you add some more complicated test (e.g. with two or more comma, escape char, etc)?
