We had kerberised the HDP cluster and storm UI was not opening and we need to troubleshoot StormUI issue.

To put DEBUG on for STormUI follow this steps:

--------------------------------------------------------------

In Ambari - Storm - Config - STORM UI Server section

add below :

ui.childopts(original)= -Xmx768m_JAAS_PLACEHOLDER

ui.childopts = -Xmx768m_JAAS_PLACEHOLDER -Dsun.security.krb5.debug=true

we wanted to troubleshoot zookeeper as well

To put DEBUG on for Zookeeper follow this steps:

------------------------------------------------------------------

In Amabri - Zookeeeper - Advanced Zookeeper-log4j
