Dear sir, I wanna know whether i can pull data from realtional database like oracle into hdfs ,or pull data from realtional database like oracle into mysql by using nifi? Should i need to develop plugins or something? Looking forward to your early reply,Thank you very much . Sincerely yours.
Re: Recommendation on getting started as a contibutor
Mark Thanks for trying. Indeed I forgot to mention in the guide that one has to add ‘nifi.properties.file.path' as ‘VM Arguments’, updating the guide now. As for logging, everything should work. Even though NiFi uses logback adapter for slf4j, the IDE setup uses log4j and all required JARs should be on the class path. Could you pleas re-verify? Here is what I see in my current setup after running ./gradlew clean eclipse -> importing project into workspace and configuring ‘Run Configurations' Run Configurations: VM arguments: -Dnifi.properties.file.path=/dev/nifi/nifi-assembly/target/nifi-0.3.1-SNAPSHOT-bin/nifi-0.3.1-SNAPSHOT/./conf/nifi.properties Working directory (“Other" is checked in): /dev/nifi/nifi-assembly/target/nifi-0.3.1-SNAPSHOT-bin/nifi-0.3.1-SNAPSHOT CLASSPATH: nifi-api-0.3.1-SNAPSHOT.jar nifi-runtime-0.3.1-SNAPSHOT.jar log4j-core-2.4.jar slf4j-api-1.7.12.jar slf4j-log4j12-1.7.12.jar jul-to-slf4j-1.7.12.jar nifi-nar-utils-0.3.1-SNAPSHOT.jar nifi-properties-0.3.1-SNAPSHOT.jar nifi-documentation-0.3.1-SNAPSHOT.jar log4j-api-2.4.jar log4j-1.2.17.jar Cheers Oleg On Oct 27, 2015, at 12:30 AM, Mark Petronic mailto:markpetro...@gmail.com>> wrote: On Mon, Oct 26, 2015 at 5:06 AM, Oleg Zhurakousky mailto:ozhurakou...@hortonworks.com>> wrote: nifi-ide-integration Oleg, thanks for the nifi-ide-integration github.

Re: Recommendation on getting started as a contibutor
Also, validate that src/main/resources is one of the source directories, so log4j.properties is pulled into the startup class path. I was just able to reproduce your exact error by disassociating it from the class path.

I verified that my working directory is correct and points to my running version of Nifi: /home/mpetronic/nifi-0.3.1-SNAPSHOT 2.

It appears you’ve misconfigured your Run Configuration. It seems like your MainClass is org.apache.nifi.bootstrap.RunNifi. It should be org.apache.nifi.NiFi Can you verify?

Re: Recommendation on getting started as a contibutor
Mark, I don't think there is a strong preference for patches vs. pull requests. A lot of contributors use pull requests, and I personally find it easier to review pull requests because you can give feedback in-line on the code. The more important thing is that whatever is being submitted should always tie back to a JIRA, and commit messages should start with the JIRA name. -Bryan On Tue, Oct 27, 2015 at 6:02 AM, Oleg Zhurakousky < ozhurakou...@hortonworks.com> wrote: > Mark > > The following output comes from RunNifi which starts org.apache.nifi.NiFi > as a separate JVM process which means you are not really in full DEBUG mode > anyway: > > opt/java/jdk1.7.0_75/bin/java > > -Dnifi.properties.file.path=/home/mpetronic/nifi-0.3.1-SNAPSHOT/./conf/nifi.properties > -Dfile.encoding=ANSI_X3.4-1968 -classpath > > /home/mpetronic/repos/nifi-ide-integration/bin:/home/mpetronic/.m2/repository/org/apache/nifi/nifi-api/0.3.1-SNAPSHOT/nifi-api-0.3.1-SNAPSHOT.jar:/home/mpetronic/.m2/repository/org/apache/nifi/nifi-runtime/0.3.1-SNAPSHOT/nifi-runtime-0.3.1-SNAPSHOT.jar:/home/mpetronic/.gradle/caches/modules-2/files-2.1/org.apache.logging.log4j/log4j-core/2.4/d99532ba3603f27bebf4cdd3653feb0e0b84cf6/log4j-core-2.4.jar:/home/mpetronic/.gradle/caches/modules-2/files-2.1/org.slf4j/slf4j-api/1.7.12/8e20852d05222dc286bf1c71d78d0531e177c317/slf4j-api-1.7.12.jar:/home/mpetronic/.gradle/caches/modules-2/files-2.1/org.slf4j/slf4j-log4j12/1.7.12/485f77901840cf4e8bf852f2abb9b723eb8ec29/slf4j-log4j12-1.7.12.jar:/home/mpetronic/.gradle/caches/modules-2/files-2.1/org.slf4j/jul-to-slf4j/1.7.12/8811e2e9ab9055e557598dc9aedc64fd43e0ab20/jul-to-slf4j-1.7.12.jar:/home/mpetronic/.m2/repository/org/apache/nifi/nifi-nar-utils/0.3.1-SNAPSHOT/nifi-nar-utils-0.3.1-SNAPSHOT.jar:/home/mpetronic/.m2/repository/org/apache/nifi/nifi-properties/0.3.1-SNAPSHOT/nifi-properties-0.3.1-SNAPSHOT.jar:/home/mpetronic/.m2/repository/org/apache/nifi/nifi-documentation/0.3.1-SNAPSHOT/nifi-documentation-0.3.1-SNAPSHOT.jar:/home/mpetronic/.gradle/caches/modules-2/files-2.1/org.apache.logging.log4j/log4j-api/2.4/cc68e72d6d14098ba044123e10e048d203d3fd47/log4j-api-2.4.jar:/home/mpetronic/.gradle/caches/modules-2/files-2.1/log4j/log4j/1.2.17/5af35056b4d257e4b64b9e8069c0746e8b08629f/log4j-1.2.17.jar:/home/mpetronic/nifi-0.3.1-SNAPSHOT/conf > org.apache.nifi.NiFi > > If you are in Eclipse, did you go through Run Configuration step where you > configure your man class that should be org.apache.nifi.NiFi? > > Oleg > > > On Oct 27, 2015, at 8:55 AM, Mark Petronic > wrote: > > > > Main Class is definitely configured to org.apache.nifi.NiFi per > > instructions.

Re: Recommendation on getting started as a contibutor
Oleg, yes, absolutely configured as a Run/Debug Configuration. I can open my debug run configuration and click "Debug" and it starts up Nifi. I've set breakpoints in a the ExecuteProcess code then created a processor from the GUI and started it and hit the break point. So, that all seems to be working.

Re: Recommendation on getting started as a contibutor
Now I am officially puzzled, since you are showing me the output from the class that is not supposed to run. Basically when you start NiFi via ./run-nifi.sh it executes org.apache.nifi.bootstrap.RunNiFi which sets the required configuration, class path etc., and starts org.apache.nifi.NiFi as a separate JVM process. That is what you see in your log which is being printed by RunNifi - 'opt/java/jdk1.7.0_75/bin/java -Dnifi.properties.file.path=/home/mpetronic/nifi-0.3.1-SNAPSHOT/./conf/nifi.properties -Dfile.encoding=ANSI_X3.4-1968 -classpath . . . org.apache.nifi.NiFi’ With these instructions we are doing the complete opposite and bypassing RunNifi executing org.apache.nifi.NiFi directly, so I can’t see how is it even possible for you to see that log statement in your Eclipse console. Could you please post a screen shots with Main and Arguments tab of your Run Configuration?

Hey Cathy, There are many processors that cover pushing/pulling from databases as well as doing some transformations.

Ah, let me demystify you... That output is NOT from the logging console. I just copied that from the the process information by right-clicking on the running process in the "Debug" view in Eclipse. However, I was doing that from home. I'm at work now and I just repeated the whole install process in my dev setup here, first forked the Nifi github and did the clean install. Then cloned nifi-ide-integration and followed the steps and it just worked!! No idea what is happening at home. But, I think I am good to go. One more tweak to your README. When you select the external directory for your sources, there is a checkbox (at least in Eclipse Luna) to "Search subfolders". That needs to be selected before I can see the source files in the debugger. Maybe obvious but I used to be a tech writer so I cannot help myself.
