Resolve Kylin Error: Java.lang.IllegalStateException

A Kylin build job executes to the third step extract Fact Table Distinct columns times wrong:

Solution: Locate the Kylin instance that performs this build task, reload metadata or restart the Kylin service (not recommended), and then build again.

Cause analysis: The meta in memory of the job server in which the build was executed was not updated and was caused by the meta execution build in the cache.
