Issue with onTimer method of KeyedProcessFunction

[V N, Suchithra (Nokia - IN/Bangalore)]

Hello,

 

We are using apache flink 1.7 and now trying to upgrade to flink 1.12.3 version. After upgrading to 1.12.3 version,  the onTimer method of  KeyedProcessFunction is not behaving correctly, the value of ReducingState and ValueState always return null.

 

Could you please help in debugging the issue.

 

Thanks,

Suchithra

Hi Zhang,

 

Please find the code snippet.

 

private ReducingState<NatLogData> aggrRecord; // record being aggregated

 

@Override

public void onTimer(long timestamp, OnTimerContext ctx, Collector<NatLogData> out) throws Exception {

// FIXME timer is not working? or re-registration not working?

NatLogData event = aggrRecord.get();   // Always get null value.

 

 

Thanks,

Suchithra
