> *PROBLEM* :
> Customer has created a Slider App by passing zookeeper quorum using below command :
> {code}
> slider create test --template appConfig.json --resources resources.json --zkhosts sandy234new1.hwxblr.com:2181,sandy234new3.hwxblr.com:2181,sandy234new2.hwxblr.com:2181
> {code}
> Below is the application log, which show us that it only picks the 1st zookeeper.
> {code}
> 2016-09-15 15:44:29,052 [main] INFO appmaster.SliderAppMaster - Loading slider-server.xml at file:/hadoop/yarn/local/usercache/root/appcache/application_1473930641993_0005/container_e04_1473930641993_0005_01_000001/confdir/slider-server.xml
> 2016-09-15 15:44:29,077 [main] INFO appmaster.SliderAppMaster - AM configuration:
> hadoop.registry.zk.quorum=sandy234new1.hwxblr.com:2181
> hadoop.registry.zk.root=/registry
> yarn.resourcemanager.scheduler.address=0.0.0.0:8030
> {code}
> *BUSINESS IMPACT* : Slider throws exceptions when 1st zookeeper goes down (Since it only picks 1st zookeeper) and this is impacting the AM.
> *STEPS TO REPRODUCE*:
> Launch a Hbase app using step 1 & 2.
> 1) slider create test --template appConfig.json --resources resources.json --zkhosts sandy234new1.hwxblr.com:2181,sandy234new3.hwxblr.com:2181,sandy234new2.hwxblr.com:2181
> This will launch a application in RM.
> From the RM UI --> application -> logs
> first line will be as below :
> {code}
