org.apache.druid.indexer.report.TaskReport.ReportMap

All Implemented Interfaces:

Serializable, Cloneable, Map<String,TaskReport>

Enclosing interface:

TaskReport

public static class TaskReport.ReportMap
extends LinkedHashMap<String,TaskReport>

Represents an ordered map from report key to a TaskReport that is compatible for writing out reports to files or serving over HTTP.

This class is needed for Jackson serde to work correctly. Without this class, a TaskReport is serialized without the type information and cannot be deserialized back into a concrete implementation.
