Any modifications you make to the Kudu build would probably need to be checked by the folks working on the Kudu project. Impala builds Kudu for 2 reasons: 1) for the client which it links against (build time dependency) 2) for the dev environment (dev and test dependency).
What are you trying to do? If you want Impala to work on ppc64le, then you'll probably eventually want Kudu to work on ppc64le as well, and that might take a lot more work/testing. If you want the impala that you build to be able to communicate with Kudu at all (whether or not Kudu runs on the same platform), you do need to compile in the client as you're currently doing. In that case, you should ask the Kudu authors at [email protected]. If you're OK with not supporting any Kudu for now, then you can "disable" Kudu support in the build/runtime. To do this, you should: 1) in native-toolchain: get source/kudu/build.sh is_supported_platform() to return false for ppc64le that results in a stub being built instead of all of kudu 2) in Impala: changing impala-config.sh so IS_KUDU_SUPPORTED is false for ppc64le.
