Description

http://releases.llvm.org/3.8.0/tools/clang/docs/UndefinedBehaviorSanitizer.html builds are supported after https://gerrit.cloudera.org/#/c/6186/, but Impala's test suite triggers many errors under UBSAN. Those errors should be fixed and then there should be a way to run the test suite under UBSAN and fail if there were any errors detected.
