Hi all,
I am facing issue when Tableau 10.2 runs query, the kylin node going down
whenever Tableau runs query.
I am not understanding what is the actual issue? Should we load the whole
data in Tableau then prepare a sheet or something other than this.
Whenever I check the kylin logs I am getting below exception.
2017-04-24 23:55:06,074 INFO [BadQueryDetector]
