Damien Hardy updated HDFS-4101:
-------------------------------
Description:
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
