----------------------------------
Summary: 高并发初始化FlinkKafkaProducer011时StateDescriptor加载报错NPE
Key: FLINK-13612
URL: https://issues.apache.org/jira/browse/FLINK-13612
Project: Flink
Issue Type: Bug
Components: Connectors / Kafka
Affects Versions: 1.7.2, 1.6.4, 1.6.3, shaded-7.0
Reporter: weiyunqing
Fix For: 1.7.2, 1.6.4, 1.6.3, shaded-7.0
org.apache.flink.streaming.connectors.kafka.FlinkKafkaProducer011#NEXT_TRANSACTIONAL_ID_HINT_DESCRIPTOR
FlinkKafkaProducer011中的NEXT_TRANSACTIONAL_ID_HINT_DESCRIPTOR变量state使用了static修饰
在执行initializeSerializerUnlessSet方法的时候高并发情况下会出现NPE异常
