**@sandeep.hadoopadmn:** I was following the same steps  
**@xiangfu0:** try out jdk 11  
**@xiangfu0:** from 0.8 pinot is built and released on jdk11  
**@sandeep.hadoopadmn:** it worked after upgrading java 11, thank you  

###  _#troubleshooting_

  
 **@sandeep.hadoopadmn:** Hi Team, What is best way running pinot services in
the background? Like when server got rebooted, pinot
services(controller,broker,zk) should start automatically.  
**@sandeep.hadoopadmn:** currently I am using nohup like nohup bin/pinot-
admin.sh StartZookeeper & in the back ground with pid, is there best way doing
this with systemctl enable service_name??  
**@mayanks:** K8s?
