> Kylin user reported max() of negative doubles does not return correct result. https://issues.apache.org/jira/browse/KYLIN-751
> The root cause is the initial value of calcite aggregator is not a negative double. In Primitive.java, it took Double.MIN_VALUE as the smallest double value but that actually is not a negative number according to javadoc.
