             Summary: buildall.sh fails with undefined CMAKE_BUILD_TYPE_LIST on Centos
                 Key: IMPALA-8475
                 URL: https://issues.apache.org/jira/browse/IMPALA-8475
             Project: IMPALA
          Issue Type: Bug
          Components: Infrastructure
    Affects Versions: Impala 3.3.0
            Reporter: Joe McDonnell
            Assignee: Joe McDonnell


A recent change added a bash array to keep track of which build types had been specified to buildall.sh. On Ubuntu, everything seems to work. On Centos, this is producing an error:
{noformat}
15:23:15 /data/jenkins/workspace/impala-asf-master-core/repos/Impala/buildall.sh: line 316: CMAKE_BUILD_TYPE_LIST[0]: unbound variable{noformat}
Given that this is on a debug build, that should mean that the CMAKE_BUILD_TYPE_LIST is empty. The current theory is that Ubuntu and Centos treat [[ -v VARNAME ]] differently, so in the following code, we are entering the block even with an empty list:
{code:java}
if [[ -v CMAKE_BUILD_TYPE_LIST ]]; then
  if [[ ${#CMAKE_BUILD_TYPE_LIST[@]} -gt 1 ]]; then
    echo "ERROR: more than one CMake build type defined: ${CMAKE_BUILD_TYPE_LIST[@]}"
    exit 1
  fi
  CMAKE_BUILD_TYPE=${CMAKE_BUILD_TYPE_LIST[0]}
fi
{code}
