Exploring Data with Apache Pig from the Grunt shell

[#1]

Hello friends -

I seem to be stuck once again as I work my way through the Hortonworks Tutorials. I am currently working "Exploring Data with Apache Pig from the Grunt shell" and stuck on the step "DUMP Movies;"

I seem to me stuck in a loop that is waiting on "sandbox.hortonworks.com/10.0.2.15/:10020. Already tried 38 times ............"

I have attached a screen for clarification.

There was one funky twist in the instruction; the tutorial calls for loading movies.txt to /user/hadoop, and several comments suggested this was a type, and the location /user/hue should be used instead. That is the only variation on the instructions I have made knowingly.

Any assistance, as always, is greatly appreciated.

Mike

@Mike Vogt How much memory have you allocated to Sandbox? Make sure that you shutdown hbase and any other component that you don't need.

Can you share screenshot of ambari?

@Mike Vogt Make sure HDFS, Mapreduce and yarn is running

port 10020 belongs job history server.

Port seems odd, what user are you running the tutorial as? @Mike Vogt I suggest creating the user you are running as so if you are root

sudo -u hdfs hdfs dfs -mkdir /user/root

sudo -u hdfs hdfs dfs -chown -R user/root

Then

hdfs dfs -put Movies.txt ./

Hi Artem -

I appreciate you looking into this. I checked the directories and permissions and they were all in order.

The issue turned out to be yarn and mapreduce needing restarts. So I restarted, and got through the immediate crisis.

But I do appreciate you taking a look nonetheless.

Cheers,

Mike

Aha! I checked Mapreduce and yarn, and they both were requiring restarts. Completed the task, and back on track.

Thanks again for your patience and guidance.
