By setting the same group id multiple processes indicate that they are all part of the same consumer group". [client.id|http://client.id/] is a concept of SimpleConsumer, its official descriptionis "The client id is a user-specified string sent in each request to help trace calls. It should logically identify the application making the request.". like this, [kafka documentation|https://kafka.apache.org/documentation/] !https://mail.google.com/mail/u/0?ui=2&ik=4365074462&attid=0.1&permmsgid=msg-a:r-5049515360704170079&th=16517a104555e5fb&view=fimg&sz=w1600-h1000&attbid=ANGjdJ9SfqqNzA50y7EDw4YMWcszL-eBrPbSpz50MbuXJjH1nI-wsVrtNw7lat5iFSi7PtVz8-eqRpldUYEHpbQQkOYhDp4PEJI9xNoP6qLeKBezQHuVwECpQm4FQtc&disp=emb&realattid=ii_jkkl3yrt1|width=562,height=102! thanks. > Modify clientId to groupId in flink-connector-kafka-0.8 > ------------------------------------------------------- > > Key: FLINK-8290 > URL: https://issues.apache.org/jira/browse/FLINK-8290 > Project: Flink > Issue Type: Improvement > Reporter: xymaqingxiang > Assignee: xymaqingxiang > Priority: Major > Labels: pull-request-available > > Now the Clientid that consumes the all topics are > constant("flink-kafka-consumer-legacy-" + broker.id()), and it is not easy > for us to look at kafka's log, so I recommend that it be modified to groupid. > We can modify the SimpleConsumerThread.java file, as shown below: > {code:java} > private final String clientId; > ... > this.clientId = config.getProperty("group.id", "flink-kafka-consumer-legacy-" > + broker.id()); > ... > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
