I'm new to Kafka and I'm test on hortonworks sanbox 2.3. I'm following kafka tutorial at
https://github.com/kafka-dev/kafka/tree/master/contrib/hadoop-consumer.
When running ./run-class.sh kafka.etl.impl.DataGenerator
test/test.properties, I get error

I already include all possible kafka jar in run-class.sh but still no luck. Please help!
You are missing jar with the class org.apache.hadoop.conf.Configuration which is not part of the Kafka library. It should be included in hadoop-common-2.5.0. You have to add this jar to the classpath.

I am trying to migrate with application startup using the Flyway programatic API, but it seems to fail to load mysql drivers.
I am using gradle everything works fine if I use command line (presummably because I can specify the driver), but I get the following error when application starts up:

This seems to be a problem of the mysql connector. I downgraded to 6.0.+ and works fine.
compile ('mysql:mysql-connector-java:6.0.+')
I have created a JAR File in the command prompt. While executing the JAR file using the command java -jar MyJAR.jar
I am getting the following error.

When I compile the file WAR, there aren't errors..
I use Jetty 7.6.0.RC4, Solr 1.4.1 and Java 7.. ;)
java.lang.ClassNotFoundException: org.apache.lucene.analysis.payloads.PayloadEncoder
This is rather self-explaining. The mentioned class cannot be found in the runtime classpath.
Make sure that the mentioned class (or at least, the JAR file containing the class) is in the runtime classpath of the webapp. One of the folders covered by the webapp's default runtime classpath is the webapp's /WEB-INF/lib folder. Drop the necessary JARs in there.
As the package name hints, that class is part of Apache Lucene library. If you need to, you can just download it from over there.
I know that this may be absolutely dumb but for the life of me I cannot figure out why I'm getting these errors in my Spring Project, it is basically from the MVC tutorial with a few modifications. This is the error I get when running my tomcat server.

You need to add org.springframework.webmvc-3.0.5.RELEASE.jar as well, as it contains the SimpleFormController class.
