Subject [jira] Commented: (HBASE-3431) Regionserver is not using the name given it by the master; double entry in master listing of servers
Date Sat, 05 Feb 2011 23:20:30 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12991081#comment-12991081
] 

Jean-Daniel Cryans commented on HBASE-3431:
-------------------------------------------

bq. Instead Master just uses the ServerName the RS volunteered.

So what happens if region server passes 127.0.0.1?

tells it use another name but we seem to go ahead and continue with our original name.
