Subject Leader Latch recovery after suspended state
Date Tue, 20 Aug 2013 17:25:16 GMT
A leader latch enters the suspended state after failing to receive a
response from the first ZK machine it heartbeats to (takes 2 thirds of the
timeout). For the last 1 third, it tries to contact another ZK machine. If
it is successful, it will enter the state reconnected.

However, on reconnect, despite the fact the original node it created in ZK
is still there, it will create another ephemeral-sequential node (the reset
method is called). This means it will relinquish leadership, if there is
another machine with a latch in the same path.

Is there any way to reconnect and reuse the original ZK node?
