Subject RE: Connection timed out error while installing "Hello Samza"
Date Thu, 21 Sep 2017 21:14:19 GMT
Yi,

Meanwhile I fixed the issue with "]# ./gradlew publishToMavenLocal" by adding apply plugin: 'maven-publish' inside the build.gradle file

Still telnet to port 9092 is not working

I also tried the next steps to run the Samza job and to consume the feed through kafka but getting below warning

2017-09-21 21:13:01.104 [main] KafkaSystemAdmin [WARN] Failed to create topic __samza_coordinator_wikipedia-feed_1: org.apache.kafka.common.errors.InvalidReplicationFactorException: replication factor: 1 larger than available brokers: 0. Retrying.

Kafka Consumer:

[root@csadatlak-wc-a1t hello-samza]# deploy/kafka/bin/kafka-console-consumer.sh  --zookeeper localhost:2181 --topic wikipedia-raw
Using the ConsoleConsumer with old consumer is deprecated and will be removed in a future major release. Consider using the new consumer by passing [bootstrap-server] instead of [zookeeper].

Yi,

It is my mistake I was looking at the previous version documentation

All the telnet worked like you showed me except for " telnet localhost 9092"
Got the cluster info as below

{"clusterInfo":{"id":1506020118416,"startedOn":1506020118416,"state":"STARTED","haState":"ACTIVE","rmStateStoreName":"org.apache.hadoop.yarn.server.resourcemanager.recovery.NullRMStateStore","resourceManagerVersion":"2.6.1","resourceManagerBuildVersion":"2.6.1 from b4d876d837b830405ccdb6af94742f99d49f9c04 by jenkins source checksum 74cda5515f4fe1fa62ab68b2bd4cd13c","resourceManagerVersionBuiltOn":"2015-09-16T21:14Z","hadoopVersion":"2.6.1","hadoopBuildVersion":"2.6.1 from b4d876d837b830405ccdb6af94742f99d49f9c04 by jenkins source checksum ba9a9397365e3ec2f1b3691b52627f","hadoopVersionBuiltOn":"2015-09-16T21:07Z"}}Connection closed by foreign host.


BTW earlier I did not execute the " Build a Samza Job Package" { was referring to .7 and this step is not part of it)

./gradlew publishToMavenLocal

When I run the above command I am getting below error

[root@csadatlak-wc-a1t hello-samza]# ./gradlew publishToMavenLocal

FAILURE: Build failed with an exception.

* What went wrong:
Task 'publishToMavenLocal' not found in root project 'hello-samza'.

* Try:
Run gradlew tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 5.786 secs

Kindly advise me for the above errors

Regards,
~Sri

Hi, Anantharaman,

Did you follow documentation here:
http://samza.apache.org/startup/hello-samza/0.13/? It states that you will need to use the following commands to install hello-samza job, in the same directory that you cloned the hello-samza git project:
{code}

mvn clean package
mkdir -p deploy/samza
tar -xvf ./target/hello-samza-0.13.0-dist.tar.gz -C deploy/samza

{code}

We apologize if the documentation is not clear and please file/open JIRA for unclear documentation issues s.t. we can fix and help.

But first, please follow the exact steps, especially when we are trying to help debugging your local deployment issue.

P.S. if all 3 services (i.e. zookeeper, kafka, and YARN) are running, are you able to telnet to those service like the response I got from my local box below:

{noformat}

And are you using VPN to access Internet on the host you are deploying Samza?
