Subject [jira] [Commented] (HBASE-10123) Change default ports; move them out of linux ephemeral port range
Date Thu, 11 Feb 2016 00:39:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10123?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15142050#comment-15142050

Yufeng Jiang commented on HBASE-10123:

After this patch, it seems that the port number 16000 conflicts with Hadoop-kms, which also
uses 16000. Users have to manually change the default port of kms to make HBase work. Is there
a more elegant way to handle this issue?

> 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.
