                 Key: IMPALA-8377

             Project: IMPALA
          Issue Type: Bug
          Components: Infrastructure
    Affects Versions: Impala 3.3.0
            Reporter: Lars Volker
            Assignee: Thomas Tauber-Marshall


Commit 25559dd4 in this change broke the build on Ubuntu 14.04: https://gerrit.cloudera.org/#/c/12824/

All daemons and any backend tests immediately segfault during startup with this stack:

{noformat}
Program terminated with signal SIGSEGV, Segmentation fault.

#8  0x0000000001b59c97 in _start ()
{noformat}

Setting {{IMPALA_KUDU_VERSION}} back to {{5211897}} in impala-config.sh make the daemons start again, as does setting {{KUDU_IS_SUPPORTED=false}}. However, only the former fixes the be-tests.

One outcome of this might be "Won't Fix" and we deprecate support for Ubuntu 14.04. I'll start a discussion on dev@ in parallel.
