I am getting this exception while launching Apache Flume :
...ANSWER
Answered 2021-Apr-20 at 21:51Your deployment on Apache Flume is using a version of Jetty older than 9.4.29 (where Attributes.unwrap()
was first introduced).
Double check the startup logs of the Jetty server, it will announce the version it thinks it is running.

QUESTION
I am new to Kafka. I have produced a kafka message named foo by kafkaSink
,a class in Flume
.When I want to consume the messages,many questions come unclear to me:
1.I have tried to use kafka-console-consumer
to consume message foo
,and it succeeded.Can I consume message foo
again with another consumer process somewhere else?
2.To the opposite,I don't want to consume message foo
again, so when I try to consume with another consumer,I should obtain nothing.How can I achieve this?
3.What if there are two messages foo
and bar
.Can I specify consumers precisely?(For example,I want process A consumes message foo
and process B consumes message bar
.To go further ,can O specify a range of message offsets? Does it have something to do with consumer group
?

- Can I consume message foo again with another consumer process somewhere else?
Yes. It can be consumed as many times as we want, either by using a new consumer group or by resetting the offset of the existing consumer group.
2.To the opposite,I don't want to consume message foo again, so when I try to consume with another consumer,I should obtain nothing.How can I achieve this?
It's all tied to a consumer group name, which typically tied to one application that is needing these messages. we need to keep the same consumer group name, and typically commited offset is retained for a week(can be changed), so, we can run the app n no of times from n different places by keeping same consumer group name, we will not consume it again, unless we reset the offset.
3.What if there are two messages foo and bar.Can I specify consumers precisely?(For example,I want process A consumes message foo and process B consumes message bar.To go further ,can O specify a range of message offsets? Does it have something to do with consumer group?
We can always consume particular message of a given partition and offset by positioning the consumer group at that offset. Its called seeking an offset, rather than seeking to earliest or latest.
QUESTION
I am currently setting an Ambari cluster and getting stuck at the ambari-web build stage
ANSWER
Answered 2021-Mar-06 at 05:02I'm sure you won't be able to do that. Because ambari will need to download the repo from hortonwork. Eventually it will still fail, since there is no public for the hortonwork from 31/01/2021.

...ANSWER
Answered 2020-Dec-18 at 15:24I managed to make it works. For those who want to know, please read this.
Firstly, change the Flume version. I use now flume 1.7.0 https://flume.apache.org/releases/1.7.0.html. But maybe a newer version would work, I don't want to break it down :)
Secondly, clone this repo https://github.com/cloudera/cdh-twitter-example. Inside, there is a flume.conf file. I configured it like that :

I'm upgrading java version in our production code from java 8 to java 11.

ANSWER
Answered 2020-Oct-13 at 13:28In case someone stumbles upon this issue... After some further looking into I believe the Apache Flume project is dead in the water and we're going to stop using it. For details please see the following:
Many open issues… no responses… https://cwiki.apache.org/confluence/display/FLUME/Developer+Section
Last version released almost 2 years ago (in the beginning it used to release every 6 months). https://flume.apache.org/index.html
Wiki not even updated with last versions - last update more then 5 years ago - https://cwiki.apache.org/confluence/display/FLUME/Home
Sadly I'm going to have to close this question in this way. Hope that helps anyone.
