> When zkfc start and zookeeper is not yet started ZKFC fails and stop directly.
> Maybe ZKFC should allow some retries on Zookeeper services like does HBase with zookeeper.recovery.retry
> This particularly appends when I start my whole cluster on VirtualBox for example (every components nearly at the same time) ZKFC is the only that fail and stop ... 
> Every others can wait each-others some time independently of the start order like NameNode/DataNode/JournalNode/Zookeeper/HBaseMaster/HBaseRS so that the system can be set and stable in few seconds
