    Description: 
Hey Guys,

Just testing the new bugfix release of 1.5.4. Happy to see that the issue of 
jobgraphs hanging around forever has been resolved in standalone/zookeeper HA 
mode, but now I'm seeing a different issue.

It looks like the HA failover is never triggered. I set up a 3/3/3 cluster of 
zookeeper/jobmanager/taskmanagers. Started my job, all fine with the new 
version. I then proceeded to kill the leading jobmanager to test the failover.

The remaining jobmanagers never triggered a leader election, and simply got 
stuck.
The logs of the remaining job managers were full of this:
