[jira] [Created] (ZOOKEEPER-1642) Leader loading database twice

Flavio Junqueira created ZOOKEEPER-1642:
-------------------------------------------

             Summary: Leader loading database twice
                 Key: ZOOKEEPER-1642
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1642
             Project: ZooKeeper
          Issue Type: Bug
            Reporter: Flavio Junqueira


The leader server currently loads the database before running leader election when trying to figure out the zxid it needs to use for the election and again when it starts leading. This is problematic for larger databases so we should remove the redundant load if possible. 

The code references are:

# getLastLoggedZxid() in QuorumPeer;
# loadData() in ZooKeeperServer.
