------------------------------
Summary: Query failed when you set
log4j.logger.org.apache.calcite=DEBUG
Key: KYLIN-3751
URL: https://issues.apache.org/jira/browse/KYLIN-3751
Project: Kylin
Issue Type: Bug
Components: Query Engine
Affects Versions: v2.5.0
Reporter: zengrui
Query failed when you set log4j.logger.org.apache.calcite=DEBUG in
kylin-server-log4j.properties.It is a NullPointerException in
VolcanoPlanner(line 891, calcite-core-1.13.0-kylin-r4), root is used before set.
Then I found that it has been solved in calcite-core-1.16.0-kylin-r2. Can I
update the calcite-core directly?
