Big Data module 2 - PIG section Chapter 3 Exercise 1 (urgent)

odesh — Wed, 21 Aug 2019 20:53:38 GMT

Hello,

I am getting error ( WARN) messages when I type pig at the LInux command line. PLease see attachment. This happens at Step 1(b).

I thought that because these are WARNings the LOAD command at Step 1(d) might still work. Unfortunately, the LOAD commnad did not work at step 3.

Please help - without loading the data I cannot do any of the PIG exercises or follow the demos on my machine.

Thanks.

Odesh.

Hi:
Answer from instructors

=== beginning of comment ===

The WARNING is the screen shot is benign. It’s just showing some logging stuff. After the student types pig at the Linux command line, the student should see the GRUNT command line, indicating the connection to the cluster is ready to go. We see this each and EVERY time we invoke pig.

Grunt>

At this point, they can start writing their LOAD statement, etc.

=== end of comment ===

In your screen shot, I think I can see the Grunt> command line toward the bottom of the screen, so it sounds like the Warning is something to expect.

Hope this helps,

Cynthia

I will try this again this morning. Yesterday, I tried this 3 times. I got the 3 WARN messages plus the Grunt> command line. I entered the LOAD command 3 times. I exited from LINUX, came back in and still the same error. I will reserve some time on VLE this morning and try it again.

In the meantime, is it possible to ask the technical people to make sure that my setup/environment is fine and not missing anything ( authorization etc ) ?

Thanks.

Odesh.

Hi:
The Module 2 image was verified. The master image on the Amazon server is working correctly when tested.
When you get the WARNING messages, the instructors said to expect those. Your screen shot did not show an error message from the LOAD command at the Grunt> prompt.

If when you do get an error message in the Virtual Lab, your report goes directly to the Technical team if you fill out the Need Help form from within the VLE. Questions in this forum are mostly for clarification of points, such as your FOREACH question. The NEED HELP icon in the VLE opens a track with the Virtual Lab support team.

The problem seems to be that there are no csv data files in the DATA folder. Please see attachment. I am sending this to both the SAS communities and the technical people. How can we load the csv files to the DATA folder ?

Regards.

Hi:
The instructors ask whether you did the steps in Chapter 1, in Exercise 1 and Exercise 2. In particular in Exercise 2, you copy data to the HDFS file system.

Hope this helps,
Cynthia
