Boyang Jerry Peng updated FLINK-19468:
--------------------------------------
Description:
If I submit a Flink job in which the stream name has a "+" character, the
metrics returned for the stream is always empty. Consider the following
example:
```
env.addSource(new TestSource()).name("testing + plus");
```
If I try to get the metrics
```
$ curl
[http://localhost:8081/jobs/5d4f28a221b2e5762f8404398a462eb0/vertices/cbc357ccb763df2852fee8c4fc7d55f2/metrics?get=0.Source__testing_+_plus.numRecordsOut]
[]
```
The metrics will always return empty. However if I remove the "+" from the
name of the stream. Metrics are returned non-empty.
Maybe it has something to do with this method:
[https://github.com/apache/flink/blob/master/flink-runtime/src/main/java/org/apache/flink/runtime/metrics/dump/MetricQueryService.java#L208]
It does not consider "+" character?
I have attached the full example to reproduce the issue.
