--------------------------------------
Summary: Slider not honoring zookeeper quorum values passed
Key: SLIDER-1169
URL: https://issues.apache.org/jira/browse/SLIDER-1169
Project: Slider
Issue Type: Bug
Components: appmaster
Affects Versions: Slider 0.91
Environment: RHEL-6 (64 Bit)
Reporter: Sandeep Nemuri
Priority: Critical
*PROBLEM* :
Customer has created a Slider App by passing zookeeper quorum using below
command :
{code}
./slider-bin/bin/slider create test --basepath
hdfs://host:port/Informatica/slider --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 customers production.
*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
