Damien Hardy commented on HDFS-4101:
------------------------------------
Actually my patch does not provide a conf entry to set number of retries like
HBase does (and the issue description let thinking)
It just provide the retries policy as soon as the service starts.
Seams to be more a bugfix in fact ?
I am not happy with the tests that duplicate a lot of code and don't tests the
limit out of bound (fails more than 3 times in fact).
But I didn't succeed in providing a polymorph method with optional parameter
setting the number of fails in getNewZooKeeper()
(I suppose I don't get well with variable scope in Mocked classe)
> ZKFC should implement zookeeper.recovery.retry like HBase to connect to

> 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
