-------------------------------
Summary: NPE when using blink planner and TemporalTableFunction
after setting IdleStateRetentionTime
Key: FLINK-19655
URL: https://issues.apache.org/jira/browse/FLINK-19655
Project: Flink
Issue Type: Bug
Components: Table SQL / Planner
Affects Versions: 1.10.0
Reporter: seunjjs
My Code here:
EnvironmentSettings bsSettings =
EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build();
final StreamTableEnvironment tableEnv = StreamTableEnvironment.create(env,
bsSettings);
tableEnv.getConfig().setIdleStateRetentionTime(Time.seconds(60),
Time.seconds(600));
final Table table = tableEnv.from("tableName");
final TableFunction<?> function = table.createTemporalTableFunction(
temporalTableEntry.getTimeAttribute(),
String.join(",", temporalTableEntry.getPrimaryKeyFields()));
tableEnv.registerFunction(temporalTableEntry.getName(), function);
And NPE throwed when I executed my program.
java.lang.NullPointerException

And When I changed to useOldPlanner, it worked fine.And when I debuged the code
,I found BaseTwoInputStreamOperatorWithStateRetention#open did not be executed.
Here is BaseTwoInputStreamOperatorWithStateRetention#open code.
public void open() throws Exception {
initializeTimerService();
if (stateCleaningEnabled) {
ValueStateDescriptor<Long> cleanupStateDescriptor =
new ValueStateDescriptor<>(CLEANUP_TIMESTAMP,
Types.LONG);
latestRegisteredCleanupTimer =
getRuntimeContext().getState(cleanupStateDescriptor);
}
}
Here is TemporalProcessTimeJoinOperator#open code.
public void open() throws Exception {
this.joinCondition =
generatedJoinCondition.newInstance(getRuntimeContext().getUserCodeClassLoader());
FunctionUtils.setFunctionRuntimeContext(joinCondition,
getRuntimeContext());
FunctionUtils.openFunction(joinCondition, new Configuration());
ValueStateDescriptor<BaseRow> rightStateDesc = new
ValueStateDescriptor<>("right", rightType);
this.rightState = getRuntimeContext().getState(rightStateDesc);
this.collector = new TimestampedCollector<>(output);
this.outRow = new JoinedRow();
// consider watermark from left stream only.
super.processWatermark2(Watermark.MAX_WATERMARK);
}
I compared the code with oldplaner(TemporalProcessTimeJoin#open).May be
TemporalProcessTimeJoinOperator#open should add super.open()?
Here is TemporalProcessTimeJoin#open code.
override def open(): Unit = {
LOG.debug(s"Compiling FlatJoinFunction: $genJoinFuncName \n\n
Code:\n$genJoinFuncCode")
val clazz = compile(
getRuntimeContext.getUserCodeClassLoader,
genJoinFuncName,
genJoinFuncCode)
LOG.debug("Instantiating FlatJoinFunction.")
joinFunction = clazz.newInstance()
FunctionUtils.setFunctionRuntimeContext(joinFunction, getRuntimeContext)
FunctionUtils.openFunction(joinFunction, new Configuration())
val rightStateDescriptor = new ValueStateDescriptor[Row]("right", rightType)
rightState = getRuntimeContext.getState(rightStateDescriptor)
collector = new TimestampedCollector[CRow](output)
cRowWrapper = new CRowWrappingCollector()
cRowWrapper.out = collector
super.open()
}
