------------------------------------------------

Ivan, 
But they are 2 different category of exceptions right?
{quote}
Recoverable errors: the disconnected event, connection timed out, and the 
connection loss exception are examples of recoverable errors, they indicate a 
problem that happened, but the ZooKeeper handle is still valid and future 
operations will succeed once the ZooKeeper library can reestablish its 
connection to ZooKeeper.

Fatal errors: the ZooKeeper handle has become invalid. This can be due to an 
explicit close, authentication errors, or session expiration.

connection loss is recoverable error right. We can reuse the zk handle as it is 
still valid. I am not sure, whether I am missing something from your point of 
view :(.

> This JIRA is to decide how to record that entries in a ledger are 
> underreplicated. 
> I think there is a common understanding (correct me if im wrong), that 
> rereplication can be broken into two logically distinct phases. A) Detection 
> of entry underreplication & B) Rereplication. 
> This subtask is to handle the interaction between these two stages. Stage B 
> needs to know what to rereplicate; how should Stage A inform it?
