tartarus created FLINK-23134:
--------------------------------
Summary: add URL decode for metric rest
Key: FLINK-23134
URL: https://issues.apache.org/jira/browse/FLINK-23134
Project: Flink
Issue Type: Bug
Components: Runtime / Metrics
Affects Versions: 1.13.0, 1.10.0
Reporter: tartarus
If the flink Operator name contains special characters, such as single quotes;
It will cause the operator's metric to be unable to be viewed through webUI;
This is because the server-side service did not decode the data.
{panel:title=Operator Name}
GroupWindowAggregate(window=[TumblingGroupWindow('w$, rowtime, 60000)],
properties=[w$start, w$end, w$rowtime, w$proctime], select=[COUNT(DISTINCT
name) AS min_uv, COUNT(name) AS min_pv, AVG(age) AS min_age_avg, MAX(age) AS
min_age_max, start('w$) AS w$start, end('w$) AS w$end, rowtime('w$) AS
w$rowtime, proctime('w$) AS w$proctime])
{panel}
`TumblingGroupWindow('w$` like this,
So I think we should decode the rest parameter.
