Hi,

Few final lines in the log are represented below for your reference.

This is the kind of message you’ll see when impala crashes. You might be able to find the
cause in the logs but I usually go straight to the core dump with gdb.

As far as instructions, I think you have everything now.

Hello,

Today, we tried building Impala on Ubuntu 15.04 x86_64 using Impala's toolchain. And unfortunately,
test data generation is failed there as well.

I think we are missing at some setup step due to which we see the issue on both platforms
(x86 as well ppc). It would be great if you could provide us any document with build and test
instructions, just to verify our setup.

Anup will be sending the latest logs on x86.

Thanks,
Nishidha

Hi Alex/Casey,

I tried to run the frontend tests with the data provided. Following is the result:
Tests run: 545, Failures: 226, Errors: 77, Skipped: 36 (See attached file: data-load-functional-exhaustive.zip)


Earlier, the number of "Errors" were 87 , so now they have reduced by 10. However, the "Failures"
count is still the same. Most of the Failures in PlannerTest and AuthorizationTest are related
to tpch (e.g. Database doesn't exist: tpch).

With regard to the directory "impala_data", i've observed that it is not being accessed/used
by any script. Are we missing on any configuration ?

Kindly guide me on this.

Regards,
Valencia

Hi Alex,

I've placed the individual testdata tars at the IMPALA_HOME/testdata/impala-data. Steps 1...10
i've already executed. Some queries about step no:11 and step no:12, that i want to clarify:

1) . bin/impala-config.sh
2) mkdir -p $IMPALA_HOME/testdata/impala-data
3) pushd $IMPALA_HOME/testdata/impala-data
4) cat /tmp/tpch.tar.gz{0..6} > tpch.tar.gz
5) tar -xzf tpch.tar.gz
6) rm tpch.tar.gz
7) cat /tmp/tpcds.tar.gz{0..3} > tpcds.tar.gz
8) tar -xzf tpcds.tar.gz
9) rm tpcds.tar.gz
10) popd

11) ./buildall.sh -notests -noclean -format
-----Here I've removed the -testdata option.
The reason to do this is to clear the previously generated partial schemas.
I think the -format option is supposed to clear out any old state. The -testdata flag is probably
needed to generate and load the test data.


12) sudo rm -rf $IMPALA_HOME/testdata/impala-data ---- Is this step required? Why?
That is only for docker. It helps to reduct the image size. You shouldn’t need to do that
or any of the other rm commands.


Could you kindly confirm on these steps ? If any corrections, please let me know.

Valencia

Hi Alex/Casey

Thank you for responding and for sharing the testdata. I'm working on using the testdata to
run the fe tests.

Meanwhile, I've posted the logs onto "Impala Dev" google group. Here's the link: https://groups.google.com/a/cloudera.org/forum/#!topic/impala-dev/zy05cHNrACk

Ahh, thanks Casey. Did not know about that.

Hi Valencia,

I'm sorry you are having so much trouble with our setup. Let's see what we
can do.

There was an infra issue with receiving the logs you sent me. The
email/attachment got rejected on our side. Maybe you can upload the logs
somewhere so I can grab them?

See more responses inline below.

Kerberos is certainly not needed to build and run tests.

Yes, the TPCH database is created and loaded as part of that first phase.
However, the data files are not yet publicly accessible. Let me work on
that from my side, and get back to you soon. One way or the other we'll be
able to provide you with the data.

The data is at https://github.com/cloudera/Impala-docker-hub/tree/master/prereqs/container_root/tmp .
The files are split into 50 MB pieces for git. You can put them back together as is done in https://github.com/cloudera/Impala-docker-hub/blob/master/complete/Dockerfile

I'll privately send you the console output from a successful FE run.
Hopefully that can help.
