Subject In the HA master mode, how to identify the alive master?
Date Thu, 05 Mar 2015 01:32:25 GMT

      In our project, we use "stand alone duo master" + "zookeeper" to make
the HA of spark master.

      Now the problem is, how do we know which master is the current alive

      We tried to read the info that the master stored in zookeeper. But we
found there is no information to identify the "current alive master".

      Any suggestions for us?
