jkosh44 opened a new pull request #1088: Use LeaderLatch to determine if oracle exists
URL: https://github.com/apache/fluo/pull/1088
 
 
   The old implementation of oracleExists checks to see if there are
   more than 1 ZNodes under the ZookeeperPath.ORACLE_SERVER path. This
   relies on the LeaderLatch implementation and uses a path given to
   a Curator recipe, which is advised against by the Curator docs.
   See https://cwiki.apache.org/confluence/display/CURATOR/TN7.
   
   The new implementation utilizes LeaderLatch to count the number
   of participants to see if there's more than 0.
