Hi Team,
I have 3 node Kylin (v2.5.0-hbase1.x) Cluster (1all+2query). I am
seeing HTTP response codes for QUERY REST APIs giving error code 500. I see
these exception when I try with concurrent requests.
Did anyone faced this issue? Am I missing any configuration in cluster
mode?
Here is exception trace on tomcat logs.
Nov 10, 2018 2:20:08 AM org.apache.catalina.core.StandardWrapperValve invoke
