[jira] [Created] (FLINK-23433) Metrics cannot be initialized in format

Fangliang Liu created FLINK-23433:
-------------------------------------

             Summary: Metrics cannot be initialized in format
                 Key: FLINK-23433
                 URL: https://issues.apache.org/jira/browse/FLINK-23433
             Project: Flink
          Issue Type: Bug
          Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
    Affects Versions: 1.11.3
            Reporter: Fangliang Liu


 
I want to use metrics in a custom format, I wrote it like this
{code:java}
ProtobufRowDeserializationSchema implements DeserializationSchema<Row>{
private transient MetricGroup metrics;
@Override 
public void open(InitializationContext context) throws Exception { 
metrics = context.getMetricGroup(); 
 }
}
{code}
But, received an `metrics` NPE. it stands to reason that the metrics have already been initialized. 

 

[~jark], [~lzljs3620320] , Looking forward to your reply.
