Subject [jira] Commented: (HBASE-961) Delete multiple columns by regular expression
Date Thu, 06 Nov 2008 08:05:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-961?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12645420#action_12645420

stack commented on HBASE-961:
-----------------------------


Why COLFAMILY_REGEX in HBaseTestCase.java and not in TestDeleteFamily.java where it is only
place used? (I'm guessing you are trying to follow a discerned patten?)

Is the regex correct?  Seems like it does not allow for the ':' columnfamily delimiter character?
 colA in your test is 'colfamily1:a' if I read it right and a regex of "col[a-zA-Z]*1" won't
match? (Whats the '1' on the end for?).

Is deleteFamilyByRegex needed?  Or is it that deleteAllByRegex can't be made do this operation?

Otherwise, patch looks great.

> Hi.
> I tried to find a way to delete multiple columns that their names match some regular
expression, but this functionality is missing (i think).
> Is it possible to add such functionality ?
