Summary: [paimon-connector]Fix Committer.createContext not passing
OperatorStateStore correctly
Key: FLINK-37860
URL: https://issues.apache.org/jira/browse/FLINK-37860
Project: Flink
Issue Type: Bug
Components: Flink CDC
Affects Versions: cdc-3.4.0
Reporter: MOBIN

source:

sink:
type: paimon
name: Paimon Sink
catalog.properties.metastore: hive
catalog.properties.uri: thrift://test:9083
catalog.properties.warehouse: hdfs://test/warehouse/
table.properties.metastore.partitioned-table: true
...{code}
The metastore.partitioned-table parameter of paimon will store partition
information in the state and trigger updates to HMS periodically. When the user
turns on this parameter, NEP exception will occur because the
OperatorStateStore is not correctly passed in Committer.createContext.
