Apache Kylin - wrong output at the first step of cube building
Few days ago kylin developers commited bypass for this kind of issue
https://github.com/apache/incubator-kylin/commit/a4692dba681bc2f136e02c64565639eb0080fcc9
Becasue sometimes hadoop may fail to get counter, even if the job succeedfrom now Kylin gives warning instead of error when failed to get cube source.
All I had to do was rebuild Kylin.
