Subject [jira] [Commented] (HBASE-10123) Change default ports; move them out of linux ephemeral port range
Date Wed, 15 Jan 2014 16:41:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10123?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13872252#comment-13872252
] 

Jonathan Hsieh commented on HBASE-10123:
----------------------------------------

I looked briefly at iana -- maybe we should get all the hadoop related projects together and
register for to get an established well known protocol port range?

http://www.iana.org/form/ports-services

This will take a while so maybe we put this patch only in trunk and keep 0.98 as is since
it would likely complicate any rolling upgrades from 0.96's.  Hopefully we can get some IANA
numbers before what follows 0.98 is out?

> Our defaults clash w/ the range linux assigns itself for creating come-and-go ephemeral
ports; likely in our history we've clashed w/ a random, short-lived process.  While easy to
change the defaults, we should just ship w/ defaults that make sense.  We could host ourselves
up into the 7 or 8k range.
