Chanhyeong Cho created FLINK-37559:
--------------------------------------
Summary: Produce warn log whenever CommitterOperator#snapshotState
called
Key: FLINK-37559
URL: https://issues.apache.org/jira/browse/FLINK-37559
Project: Flink
Issue Type: Bug
Affects Versions: 1.20.1
Reporter: Chanhyeong Cho
Too many 'pendingCommittables' Name collision logs are produced due to the
reasons mentioned in the title.
{code:java}
Name collision: Group already contains a Metric with the name
'pendingCommittables'. Metric will not be reported.[<ip address>, taskmanager,
<tm host>, <job name>, <task name>: Committer, <task index>] {code}
We've started use flink 1.20.1, and don't know about previous versions.
I guess this occurs after change of
https://issues.apache.org/jira/browse/FLINK-36455.
CommitterOperator#snapshotState raise CommittableCollector#copy, and that calls
SinkCommitterMetricGroup#setCurrentPendingCommittablesGauge which registers
'pendingCommittables' gauge into metricGroup.
Because the 'pendingCommittables' gauge was already registered at creation
time, it produces warn message at every 'copy()' called.
