[jira] Commented: (HADOOP-6487) Support ranges in hosts file

    [ https://issues.apache.org/jira/browse/HADOOP-6487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12799316#action_12799316 ] 

Todd Lipcon commented on HADOOP-6487:
-------------------------------------

Seems to me the only reasonable way to do this would be either (a) IP/netmask or (b) regular expression. Otherwise, how could one distinguish between abc1-20.com meaning abc1 through abc20 compared to a host called abc1-20?

> It would be nice to have a range support for hosts file. For example host files could look like
> {code:title=hosts.include|borderStyle=solid}
> abc1-10.com
> abc21-30.com
> {code}
> {code:title=hosts.exclude|borderStyle=solid}
> abc1-5.com
> {code}
