Class TezTimelineClient

java.lang.Object

DAGClient

cascading.stats.tez.util.TezTimelineClient

All Implemented Interfaces:

TimelineClient

public class TezTimelineClient
extends DAGClient
implements TimelineClient

TezTimelineClient is currently just a proxy around DAGClient that pretends to implement TimelineClient (throws errors on all methods).

When TEZ-3369 is implemented, TezTimelineClient can be replaced by a pure DAGClient usage. Until then, FlowStats is non-functional.
