Hi,
we are trying to use Hudi in aws Kinesis Data Analytics Studio along with
Flink.
The following python code produces data and inserts it into kinesis stream:
```
def getReferrer():
data = {}
now = datetime.datetime.now()
str_now = now.isoformat()
data['uuid'] = str(uuid.uuid4())
data['event_time'] = str_now
data['ticker'] = random.choice(['AAPL', 'AMZN', 'MSFT', 'INTC', 'TBV'])
price = random.random() * 100
data['price'] = round(price, 2)
return data
while True:
data = json.dumps(getReferrer())
print(data)
res = kinesis.put_record(
StreamName="stream-name",
Data=data,
PartitionKey="partitionkey")
time.sleep(1)
```
In Zeppelin, we create a table as a source ingesting the above generated
data:
```
%flink.ssql(type=update)
drop table stock_table;
CREATE TABLE stock_table (
uuid varchar(36),
ticker VARCHAR(6),
price DOUBLE,
event_time TIMESTAMP(3),
WATERMARK FOR event_time AS event_time - INTERVAL '5' SECOND
)
PARTITIONED BY (ticker)
WITH (
'connector' = 'kinesis',
'stream' = 'stream-name',
'aws.region' = 'us-west-2',
'scan.stream.initpos' = 'LATEST',
'format' = 'json',
'json.timestamp-format.standard' = 'ISO-8601');
```
Next, we create a table source for hudi on S3:
```
%flink.ssql(type=update)
drop table t1;
CREATE TABLE t1(
uuid VARCHAR(36),
ticker VARCHAR(6),
price DOUBLE,
ts TIMESTAMP(3)
)
PARTITIONED BY (ticker)
WITH (
'connector' = 'hudi',
'path' = 's3://bucket-name/hudi/',
'table.type' = 'MERGE_ON_READ' -- this creates a MERGE_ON_READ table, by
default is COPY_ON_WRITE
);
```
And finally, we want to insert data from stream into s3 using hudi:
```
%flink.ssql(type=update)
-- insert data using values
INSERT INTO t1 select uuid, ticker, price, event_time as ts from stock_table;
```
We get the following error when trying to run the above code:
```

We tried all the jar files as custom connectors,
`hudi-flink-bundle_2.11-0.9.0.jar` and `hudi-flink-bundle_2.11-0.8.0.jar` and
`hudi-flink-bundle_2.11-0.7.0.jar` downloaded from
[here](https://repo1.maven.org/maven2/org/apache/hudi/hudi-flink-bundle_2.11/).
You advice/assistance in this matter is much appreciated.
