----------------------------------------
Hi again,
I've found out what happened. The patch which has been tested is the one
uploaded for 3.5.0 release.
How can I deal with these two patches in order to be tested by Hadoop QA in
their corresponding branches? Or should I upload the 3.5.0 patch to other
place/ticket?

> FastLeader election takes long time because of the exponential backoff.
> Currently the time is 60 seconds.
> It would be interesting to give the possibility to configure this parameter,
> like for example for a Server shutdown.
> Otherwise, it sometimes takes so long and it has been detected a test failure
> when executing: org.apache.zookeeper.server.quorum.QuorumPeerMainTest.
> This test case waits until 30 seconds and this is smaller than the 60 seconds
> where the leader election can be waiting for at the moment of shutting down.
> Considering the failure during the test case, this issue was considered a
> possible bug.
