Hi Poorna,
I was able to resolve this with James' help in PHOENIX-3259 by deleting
the guava jar in the HBase distribution and replacing it with the
guava-13 jar.
Thanks,
Francis

Hi Francis,
(Apology for the delayed response, I was out of office for the past few
weeks.)
Do you see a guava-13 jar in the classpath of Tephra? It should be in
<tephra-home>/lib directory. You can define environment variable CLASSPATH
pointing to path of guava-13 jar before starting Tephra. This will put
guava-13 jar earlier in Tephra's classpath.
Thanks,
Poorna.

Hi Poorna,
Thanks, that narrows down the problem. I was spinning up a few VMs with
various versions of Ubuntu and their kernels, but that didn't shed any
light on the problem.
You mentioned that adding the guava-13 jar to the classpath before the
guava-12 jar would be a workaround. I am using Phoenix 4.8.1-rc0, so what
would be the best way to do this?
Cheers,
Francis

Hi Francis,
This is due to guava-12 vs guava-13 incompatibility [1]. Tephra depends on
guava-13 and HBase depends on guava-12. Depending on how the OS orders the
jars in the classpath, sometimes guava-12 may appear earlier in the
classpath. This leads to the NoSuchMethodError exception. We are planning
on removing Tephra's dependency on guava-13 in the next release. Until
then
a workaround is to add guava-13 jar into the classpath before guava-12
jar.
Thanks,
Poorna.

Hi Poorna,
That would be very helpful! Unfortunately, I ran into the same issue
where
the image no longer works correct on my dev environment, but works
properly
on travis.
I am not receiving this error:

This is the exact same problem I encountered and posted on the list about
previously: https://mail-archives.apache.org/mod_mbox/phoenix-user/20160
3.mbox/%[email protected]%3E
It's puzzling that an identical image will behave differently on
different
systems. Does tephra use any kernel functionalities directly?
Cheers,
Francis

Hi Francis,
Tephra startup script redirects all logs to a file by default. To help
debug such issues, you could update the Tephra startup script [1] to log
everything to stdout instead of a file when running inside docker. We
are
also planning on adding a --foreground option to Tephra startup script,
in
which case the logs will be written to stdout directly. This will help
in
debugging in future.
Thanks,
Poorna.

I was able to get it to run reliably with Phoenix 4.8.1-rc0. Another
part
of the equation was forcing travis to use their Ubuntu 14.04
environment
rather than the default 12.04 environment. I am assuming 12.04 had an
older
kernel which prevent docker images from working correctly.

Hi all,
I have created a docker image containing HBase 1.2.3 and Phoenix
4.8.0.
See: https://github.com/Boostport/hbase-phoenix-all-in-one
When running tests against the image on my machine, tephra works
perfectly.
However, tephra seems to be unreliable in CI environments. It seems
that
the tx service is not discovered:
RuntimeException: java.lang.Exception: Thrift error for
org.apache.tephra.distributed.TransactionServiceClient$2@3e9e291e:
Unable to discover tx service. -> Exception: Thrift error for
org.apache.tephra.distributed.TransactionServiceClient$2@3e9e291e:
Unable to discover tx service. -> TException: Unable to discover tx
service.
Here's a build on wercker which shows tephra failing:
https://app.wercker.com/boostport/avatica/runs/build/57e9b5d
170a35501008402b4?step=57e9b5f72c15ad000127a534
I also tried travis, but the same issue occurs:
https://travis-ci.org/Boostport/avatica/builds/162952367
Since I am unable to ssh into those docker container on wercker or
travis, it is hard to debug what's causing tephra to fail. I am hoping
that
the issue is related to TEPHRA-179 (and a few other JIRAs related to
it)
which I reported a few weeks ago and has since been fixed.
Has anyone else ran into similar problems? I would love to hear your
thoughts.
Cheers,
Francis
