########## File path: exec/java-exec/src/main/java/org/apache/drill/exec/physical/config/HashJoinPOP.java ########## @@ -32,35 +33,53 @@ import com.google.common.base.Preconditions; import com.google.common.collect.Lists; import org.apache.drill.exec.physical.base.AbstractJoinPop; +import org.apache.drill.exec.work.filter.RuntimeFilterDef; + @JsonTypeName("hash-join") +@JsonIgnoreProperties(ignoreUnknown = true) Review comment: The primary reason is to backward compatible. PhysicalPlans without `runtimeFilterDef` property (maybe not support RuntimeFilter) can still work out. That is the `ignoreUnknown=true` usage. The `@JsonIgnore` is to not output the property content as the final json. That's not our target. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
