Canceling a timer by ID is not yet supported in InMemoryTimerInternals

Got the following exception with spark runner and GroupIntoBatches transform:

Caused by: java.lang.UnsupportedOperationException: Canceling a timer by ID is not yet supported.
    at org.apache.beam.runners.core.InMemoryTimerInternals.deleteTimer(InMemoryTimerInternals.java:158)
    at org.apache.beam.runners.core.SimpleDoFnRunner$TimerInternalsTimer.clear(SimpleDoFnRunner.java:1198)
    at org.apache.beam.sdk.transforms.GroupIntoBatches$GroupIntoBatchesDoFn.processElement(GroupIntoBatches.java:474)

 

The InMemoryTimerInternals.deleteTimer with a timeDomain is not supported:

public void deleteTimer(
StateNamespace namespace, String timerId, String timerFamilyId, TimeDomain timeDomain)

{ throw new UnsupportedOperationException("Canceling a timer by ID is not yet supported."); }

However, this function is called by SimpleDoFnRunner$TimerInternalsTimer.clear:

public void clear()

{ this.timerInternals.deleteTimer(this.namespace, this.timerId, this.timerFamilyId, this.spec.getTimeDomain()); }

Which is called by GroupIntoBatches$GroupIntoBatchesDoFn.processElement.
