   > Could you take a look at this @ferdelyi? I saw that you worked on both 
#5638 and #6114.
   > 
   > I moved some code that you added from ZKCuratorManager to SecurityUtil, so 
I could use it when we are using ZooKeeper without Curator in ZKFC. I also did 
some changes in Yarn in this patch, where I am creating an ActiveStandbyElector 
with a TruststoreKeystore based on the Yarn SSL configs. Do you think it is the 
right way to do that?
   
   Thank you @dombizita for reaching out. We discussed it in a call. Looks good 
to me and great work!

> HADOOP-18709 added support for Zookeeper to communicate with SSL/TLS enabled 
> in hadoop-common. With those changes we have the necessary parameters, that 
> we need to set to enable SSL/TLS in a ZK Client.
> In YARN-11468 the SSL communication can be set in Yarn, now we need to 
> similar changes in HDFS to enable it correctly. In HDFS ZK Client is used in 
> the Failover Controller. In this improvement we need to create the ZK client 
> with the necessary SSL configs if we enable it, which we can track under a 
> new HDFS config.
