I am getting the following errors while running compiling the Google dataflow example on the cloud instance. I am trying to run the streaming example by the name of StreamingWordCount using the following command
mvn compile exec:java -Dexec.mainClass=com.google.cloud.dataflow.examples.complete.StreamingWordCount.java
Is there something that I am doing wrong?Any help is appreciated.
Thanks

Exception
You seem to be attempting to run the StreamingWordCount example that comes with the Google Cloud Dataflow SDK for Java. The example under that name doesn't exist -- hence, the exception you are seeing.
You likely want to run WindowedWordCount instead, an example that shows how to run the same pipeline over either unbounded PCollections in the streaming mode or bounded PCollections in the batch mode.
Please follow the instructions here.

in the line:
Downloading from company-releases: https://artifactory.**.de/artifactory/**/1.0.2/*-1.0.2.pom
maven looks at the correct place. I'm able to download it with curl:
curl -u username:password -X GET "https://artifactory.**.de/artifactory/**/1.0.2/*-1.0.2.pom"
but if I paste that path into Chrome, I get an 404 Error.
I also configured the settings.xml in my C:/Users/Username/.m2/ folder:
<server>
<id>company-releases</id>
<username>my_username</username>
<password>my_password</password>
</server>
I also checked the possible errors of the Link shown at the bottom of the log, but as I'm able to "curl" it these don't seem to be the reasons. Currently I'm out of ideas. I hope you can help me :) Please tell me if you need to see additional sources.
okay, the solution was to set preemptive authentification in settings.xml:
for example:
<server>
<username>*****</username>
<password>*****</password>
<id>central</id>
<configuration>
<httpConfiguration>
<all>
<usePreemptive>true</usePreemptive>
</all>
</httpConfiguration>
</configuration>
</server>
Explanation: maven first tries to request without authentification. If the Repo is private (this means that without authentification, artifacts are hidden), jfrog artifactory responses with 404 instead of unauthenticated. After 404 maven doesn't try again, but sees it as failed.

I am new to using Hadoop, and I am currently trying to run wordcount on a single node cluster on my ubuntu desktop. I am trying to follow this guide to run the hadoop job:
http://javabeginnerstutorial.com/hadoop/your-first-hadoop-map-reduce-job/
Currently I am stuck on step 3, when I try to mvn clean install, this is the error I receive. I am using the exact same pom.xml file that is linked on step 3. Was I supposed to edit something in the pom.xml file in order to successfully compile? Or do the links possibly not work? Any help would be great. Thanks.
