[jira] [Updated] (ZOOKEEPER-1082) modify leader election to correctly take into account current epoch

     [ https://issues.apache.org/jira/browse/ZOOKEEPER-1082?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Flavio Junqueira updated ZOOKEEPER-1082:
----------------------------------------

    Attachment: ZOOKEEPER-1082.patch

Preliminary patch. It is backward compatible, and tests pass for me. Also, FLELostMessageTest has notification messages hardcoded, which shows that it is backward compatible, but we probably want to implement a little more testing.
