Subject [jira] [Commented] (ACCUMULO-1286) getMasterLocations never returns more than one master
Date Sun, 27 Oct 2013 18:31:30 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1286?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13806413#comment-13806413

Josh Elser commented on ACCUMULO-1286:
--------------------------------------

Looking at some code, we don't have anything in ZooKeeper to track how many (if any) stand-by
masters we have. Unless I'm missing something, it looks like each master should be referencing
a node in ZK for itself (host+port) so that we can track all masters as well as the active
master.
