-------------------------------------
Summary: NoRealizationFoundException due to creating a wrong
JoinDesc
Key: KYLIN-3902
URL: https://issues.apache.org/jira/browse/KYLIN-3902
Project: Kylin
Issue Type: Bug
Components: Query Engine
Reporter: Zhong Yanghong
Assignee: Zhong Yanghong
When joining with a lookup table, a column from fact table is used more than
once, the JoinDesc will not be correctly generated in *OLAPJoinRel*, causing
NoRealizationFoundException. Multimap should be used instead of Map.
Sample Join:
{code}
select LSTG_FORMAT_NAME, count(*)
FROM TEST_KYLIN_FACT
INNER JOIN EDW.TEST_CAL_DT as TEST_CAL_DT
ON TEST_KYLIN_FACT.CAL_DT = TEST_CAL_DT.CAL_DT AND TEST_KYLIN_FACT.CAL_DT =
TEST_CAL_DT.WEEK_BEG_DT
group by LSTG_FORMAT_NAME
{code}
