Hi Kurt：
I had the same mistake.
sql:
insertinto
dw_access_log select get_json_value(query_nor, query_nor_counter) as`value`from
ods_access_log_source groupby tumble (time_key, interval'1'MINUTE),
group_key
get_json_value
public class GetJsonValue extends AggregateFunction<String, Map<String, Long>> {
@Override
public boolean isDeterministic() {
return false;
}
@Override
public Map<String, Long> createAccumulator() {
return new HashMap<>();
}
@Override
public void open(FunctionContext context) throws Exception {
}
public void accumulate(Map<String, Long> datas, String key, long value) {
datas.put(key, value);
}
@Override
public String getValue(Map<String, Long> acc) {
return JSON.toJSONString(acc);
}
@Override
public TypeInformation getResultType() {
return Types.STRING;
}
}
Best forideal

Thank you. It is an online job and my input is huge. I check the trace and find
that the array is resized when the array is not enough. The code is as below:
public void add (int value) {
int[] items = this.items;
if (size == items.length) items = resize(Math.max(8, (int)(size * 1.75f)));
items[size++] = value;
}
Only blink planner has this error. Can it be a thread-safe problem or something
else? I will try to reproduce it locally.

Hi,
Are you using versions < 1.9.2? From the exception stack, it looks like caused
by FLINK-13702, which is already fixed in 1.9.2 and 1.10.0.
Could you try it using 1.9.2?
Best,
Jark

I would suggest you set break points in your code. Step through the code, this
method should show you which array variable is being passed a null argument
when the array variable is not null able.

I am using Roaring64NavigableMap to compute uv. It is ok to us flink
planner and not ok with blink planner. The SQL is as following:
SELECT toLong(TUMBLE_START(eventTime, interval '1' minute)) as curTimestamp, A,
B, C, D,
E, uv(bitmap(id)) as bmp
FROM person
GROUP BY TUMBLE(eventTime, interval '1' minute), A, B, C, D, E
The udf is as following:
public static class Bitmap extends AggregateFunction<Roaring64NavigableMap,
Roaring64NavigableMap> {
@Override
public Roaring64NavigableMap createAccumulator() {
return new Roaring64NavigableMap();
}
@Override
public Roaring64NavigableMap getValue(Roaring64NavigableMap accumulator) {
return accumulator;
}
public void accumulate(Roaring64NavigableMap bitmap, long id) {
bitmap.add(id);
}
}
public static class UV extends ScalarFunction {
public long eval(Roaring64NavigableMap bitmap) {
return bitmap.getLongCardinality();
}
}
