Daniel Templeton commented on HADOOP-2689: ------------------------------------------ I've pulled together a short gawk script that handles the unrolling of regex-esque syntax quite nicely. Since slaves.sh already depends on sed, I don't see any issue swapping out that dependency for gawk. I just need to do a little more clean-up, and then I'll post the patch. > RegEx support for expressing datanodes in the slaves conf files > --------------------------------------------------------------- > > Key: HADOOP-2689 > URL: https://issues.apache.org/jira/browse/HADOOP-2689 > Project: Hadoop Common > Issue Type: Improvement > Components: conf > Affects Versions: 0.14.4 > Environment: All > Reporter: Venkat Ramachandran > > It will be very handy if datanodes and task trackers can be expressed in the > slave conf file as regular expressions. > For example, > machine[1-200].corp > machine[400-679].corp -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
