Shaofeng SHI commented on KYLIN-761:
------------------------------------
A workround for this problem from community user:
Since missing classes were available within below jars files in
WEB-INF/lib, but classes are not getting loaded due to some weird reasons.
Though I will investigate it, but for time being issue is resolved by
creating a soft link to below jars from tomcat/lib.
“kylin-query-0.7.1-incubating-SNAPSHOT.jar"
“calcite-core-0.9.1-incubating.jar”
> Tables are not shown in the "Query" tab, and couldn't run SQL query after
> cube be built
