Fix Version/s: (was: v3.0.0-beta)
v3.1.0
> NPE while executing a query with two left outer joins and floating point expressions on nullable fields
> -------------------------------------------------------------------------------------------------------
>
> Key: KYLIN-3121
> URL: https://issues.apache.org/jira/browse/KYLIN-3121
> Project: Kylin
> Issue Type: Bug
> Components: Query Engine
> Affects Versions: v2.2.0
> Environment: HDP 2.5.6, Kylin 2.2.0
> Reporter: Vsevolod Ostapenko
> Assignee: nichunen
> Priority: Major
> Fix For: v3.1.0
>
>
> Queries that include two (or more) left outer joins and contain floating point expressions that operate on the fields that contain integer NULL values (due to left outer join) fail in-flight with NullPointerExceptions.
> As an example, the following query generates NPE on either of the two expressions:
> * 100.0 * t2.media_gap_call_count
> * 1.0 * NULLIF(t1.active_call_count, 0)
> with
