The patch for this is finally out: https://gerrit.cloudera.org/#/c/11363/
I put some work into trying to make sure this will be as seamless as possible for everyone. - For people on Ubuntu 16 or the other CDH supported distros, you'll automatically start using the CDH Kudu. - For people on Ubuntu 14, Impala will automatically set USE_CDH_KUDU=false and fall back to the toolchain Kudu. You should see no change. - For people who want to develop on other OSes, KUDU_IS_SUPPORTED will get set to false, we will build a stub Kudu client, and you should be able to build and run as normal, except that Kudu related operations will fail. Or you can build Kudu locally and link Impala against it using the KUDU_CLIENT_DIR/KUDU_BUILD_DIR variables I also filed IMPALA-7515 <https://issues.apache.org/jira/browse/IMPALA-7515> to track the eventual removal of toolchain Kudu support On Wed, Aug 22, 2018 at 11:31 AM Thomas Tauber-Marshall < tmarsh...@cloudera.com> wrote: > So the toolchain binaries are provided for: centos5,6,7, debian7,8, > sles11,12, ubuntu14,16 > The new CDH component binaries will be available for: redhat6,7, debian8, > sles12, ubuntu16 > so we would be dropping easy support for building on basically centos5, > debian7, sles11, and ubuntu14 > > For people who want to develop on other oses like Ubuntu 18.04, it would > still be possible by compiling Kudu locally and using the > KUDU_CLIENT_DIR/KUDU_BUILD_DIR variables. > > I'm also strongly leaning towards hiding this functionality behind a flag > for now (not many people chimed in on this thread, but I suspect there are > still a decent number of people developing on Ubuntu 14 who I'll get angry > emails from if they rebase and discover they have to upgrade their os), in > which case building the toolchain would remain a viable option for using > other oses as well, as least for now. > > On Tue, Aug 21, 2018 at 4:47 PM Tim Armstrong <tarmstr...@cloudera.com> > wrote: > >> Is there a path to building a version of Kudu locally for an arbitrary >> linux distro? >> >> Personally I am less concerned about 14.04 support and more concerned >> about >> what the path to upgrading to 18.04.
