Subject [GitHub] [zookeeper] vladimirivic opened a new pull request #953: ZOOKEEPER-3398 Learner.connectToLeader() may take too long to time-out

vladimirivic opened a new pull request #953: ZOOKEEPER-3398 Learner.connectToLeader() may take
too long to time-out 
URL: https://github.com/apache/zookeeper/pull/953
 
 
   After leader election happens, the followers will connect to the leader which is facilitated
by the Learner.connectToLeader() method. 
   
   Learner.connectToLeader() is relying on the initLimit configuration value to time-out in
case the network connection is unreliable. This config may have a high value that could leave
the ensemble retrying and waiting in the state of not having quorum for too long. The follower
will retry up to 5 times. 
   
   This patch introduces a new configuration directive that will allow Zookeeper to use different
time-out value `connectToLeaderLimit` which then could be set to lower value than `initLimit`.
   
   Test plan:
   - ant clean 
   - ant test-core-java
   
   NOTE: Lots of whitespace changes, hope it helps.
