Subject [jira] Commented: (HADOOP-6787) Factor out glob pattern code from FileContext and Filesystem
Date Wed, 02 Jun 2010 17:05:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12874665#action_12874665

Eli Collins commented on HADOOP-6787:
-------------------------------------

I agree Jakob, GlobPattern should be package private like GlobFilter. The annotations should
be the same as other package private hadoop.fs classes. Globbing is not internal to HDFS it's
purely client side, used by FsShell for any file system.

> The GlobFilter class (especially the error-prone setRegex method) is duplicated in both
FileContext and Filesystem. And I'd like to be able to reuse the most of the setRegex code
for glob pattern matching in metrics filter configurations.
> We could at least factor out the hairy setRegex code and package them into a GlobPattern
class with a minimum compile method.
